Before beginning, use the given conversion for meters to miles provided by your teacher (If given one). If instructed to use less decimal places, do so.
Start with the “numerator” of what you are looking for. Use a conversion equal to that numerator to advance your formula. (In this case 1 mile is equal to 1609.34 meters). With double conversions, the given rate will always end up in the middle of your equation. (In this case, meters per second). Finally, using equivalent conversions, advance your equation until you end with the “denominator” of what you are looking for. (In this case, hours). This number will always end on the bottom of a double conversion equation.
Using your calculator, open a parenthesis, multiply all numbers across the top of the equation. Close parenthesis. Hit “divide” on calculator, open another parenthesis and multiply all numbers across the bottom of the equation. Close parenthesis and hit “enter”.
(1x25x60x60) / (1609.34x1x1x1) = 55.923546 mi/hr
* Note: using parenthesis in your calculator is essential for your calculator to perform the correct function.
* Round your answer to correct amount of decimal places (per teacher instruction) and scientifically notate if necessary.
* Don’t forget to “box” your answer if required by instructor.

Your spaceship lands on an unknown planet. To determine the characteristics of this planet, you drop a wrench from 3.50 m above the ground and measure that it hits the ground 0.809 s later.
Assuming that the planet has the same density as that of earth (5500 kg/m3), what is the radius of the planet?
Answers
Explanation:
By the formula,
[tex]s=ut+\frac12at^2[/tex]
[tex]-3.5=0+\frac12a(0.809)^2[/tex]
[tex]a=-10.659 ms^{-2}[/tex]
where a is the acceleration of objects by gravity.
We also know that by the Law of Gravitation,
[tex]F=-\frac{GMm}{r^2}=ma[/tex]
[tex]a=-\frac{GM}{r^2}[/tex]
The mass of the planet is given by
[tex]M=\rho V=\rho(\frac 43\pi r^3)[/tex]
So
[tex]a=-\frac{G(\rho\frac 43\pi R^3)}{r^2}= - \frac{(6.67 \times 10^{-11})(5500)(\frac43)\pi R^3}{(R+3.5)^2} = -10.659[/tex]
Since R>>3.5, so we approximate
[tex](R+3.5)^2\approx R^2[/tex]
Solving the last equation,
[tex]R=6936.483 km[/tex]

Question 4 A car of mass 820 kg has a maximum power of 30 kW and moves against a constant resistance of motion to 910 N. Calculate the maximum speed of the car in the following situation; b)Up an incline (hill) of 8.75° to the horizontal?
Answers
Answer:
P = W / t = m g s / t = m g v where work by auto = m g s
30 kw = 30000 watts = 30000 J / s
Work wasted = F v as shown above relating work and power
Work done against incline = m g s sin 8.75 and power against incline
= m g v sin 8.75 = 1222 v Joules / sec
power in moving auto = power available - power lost to friction
power in moving auto = 30000 - resistance = 30000 - 910 v
1222 v = 30000 - 910 v
v = 30000 / 2132 = 14 m/s
Note: constant resistance to motion must mean P = W / t = F s / t = F v
Maximum speed will be v = 14.07 m/s
What is power ?Power is defined time rate of doing work or delivering energy.
Work done = Force * displacement
Power = work done / time
= (Force * displacement ) / time
since , displacement / time = velocity
Power = force * (displacement / time ) = force * velocity
Power = mass * acceleration * velocity ( as force = mass * acceleration)
since , car is travelling up in an incline of 8.75° to the horizontal
hence , it will have two components of velocity
vertical component = v sin (theta ) = v sin(8.75°)
horizontal component = v cos (theta)= v cos (8.75°)
Power = m* a * v sin (theta )
= 820 * 9.8 * v *sin (8.75°) ( a = g = 9.8 m[tex]/s^{2}[/tex])
= 1221.472 v
Power lost due to resistance in motion = 910 * velocity = 910 v
Power = Total power - power lost due to resistance in motion
= 30 * [tex]10^{3}[/tex] - 910 v
30 * [tex]10^{3}[/tex] - 910 v = 1221.472 v
v = 14.07 m/s
Maximum speed will be v = 14.07 m/s

1. An MR-2 starts from rest and accelerates westward to a speed of 27 m/s in
11.8 seconds.
a) What is its acceleration?
b) What is the displacement it covered?
Answers
Answer:
a) 2.28 m/s²
b) 159.86 m
Explanation:
Part A:
u = 0 m/s
v = 27 m/s
t = 11.8 seconds
a = ?
Formula:
v = u + at
=> 27 = 0 + a(11.8)
=> 27 = a(11.8)
=> a(11.8) = 27
=> a = 27/11.8
=> a = 2.28 m/s²
Part B:
s = ?
Formula:
s = (v² - u²)/2a
s = (27² - 0²) /2(2.28)
= 729/4.56
= 159.86 m

What is Newton's second law of motion ?
Newton's second law of motion states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
Initial mass = 950 kg
mass of piolet = 65 kg
reduced mass = 950 - 65 = 885 kg
according to Newton's second law of motion
force = mass * acceleration
3000 N = 885 kg * acceleration
acceleration = 3000 / 885 = 3.39 m/s^2 = 3.4 m/s^2

Suppose 2kg of glycerine have a temperature of 30°C. Heat is supplied to a steady rate of 100W. The temperature after 35 minutes is 75°C.
Calculate the specific heat capacity of glycerine.
Answers
Answer:
210000.................
The specific heat capacity of glycerine is 2333.3 J/(kg·K).
We can use the formula for heat (Q) absorbed by a substance:
Q = mcΔT
Where Q is the heat absorbed, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
We know the mass of glycerine (m = 2 kg), the time for which heat is supplied (t = 35 minutes = 2100 seconds), the rate of heat supply (P = 100 W), the initial temperature (T1 = 30°C = 303 K), and the final temperature (T2 = 75°C = 348 K).
First, we need to calculate the total heat absorbed by the glycerine:
Q = Pt
Q = 100 W × 2100 s
Q = 210000 J
Next, we can calculate the change in temperature:
ΔT = T2 - T1
ΔT = 348 K - 303 K
ΔT = 45 K
Finally, we can calculate the specific heat capacity of glycerine:
c = Q/(mΔT)
c = 210000 J/(2 kg × 45 K)
c = 2333.3 J/(kg·K)
Therefore, the specific heat capacity (c) = 2333.3 J/(kg·K).
