a ball is moving with a velocity of 0.5 m/s its velocity is decreasing at the rate of 0.05 m/s² what is its velocity in 5 seconds? how much time will it take from start to stop?what is the distance to travelled by it before stopping?
Answers
Answer:
v after 5s = 0.25 m/s, it took 10s to stop, it has traveled 2.5m before stopping
Explanation
We can use the equation of motion with constant acceleration
Given: v0= 0.5 m/s a= -0.05 m/s²
v(5s) = v0 + a×t = 0.25 m/s
Stop => v=0 => v0 + a×t = 0 => t=10s
Distance at t=10s ⇒ x(10) = 0.5×10 + 0.5x(-0.05)x10² = 2.5m

60.96-mile distance in kilometers
Answers
Answer:
98.105610 Kilometers
Explanation:
Rounded to 8 digits
Answer:
98.11 km
Explanation:
60.96 mi (5280ft/mi)(12 in/ft)(2.54 cm/in)(1 m/ 100cm)(1 km/1000 m) = 98.10561024 km
however, reporting this precision to the nearest hundred millionth of a kilometer is silly as we only know the mile dimension to the nearest hundredth of a mile.
A hundredth of a mile is 5280/100 = 52.8 ft or just over 16 m
It would only be a little bit of a presumption to give our precision to the nearest 10 meters as I have done.
This also fits neatly into the significant digits rule. Both the original dimension and the converted dimension have four significant digits.
25m/s to miles/hr step by step
Answers
55.9235462985 mi/hr
Or scientifically notated 5.59235462985 mi/hr
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.
Forces is F1(east) and F2 are simultaneously applied to
a 30kg mass. When f2is east , a = 5.0 m/s2 east and
When F2 is west a=10m/s² east - Determine the
Magnitude of f1 and f2
Answers
There's a problem with the given information, but I'll get to that later.
Use Newton's second law. When F₂ points east, we have
F₁ + F₂ = (30 kg) (5.0 m/s²) = 150 N
and when F₂ points west, it acts in the opposite direction and
F₁ - F₂ = (30 kg) (10 m/s²) = 300 N
Solve for F₁ and F₂ : we have
(F₁ + F₂) + (F₁ - F₂) = 150 N + 300 N
2F₁ = 450 N
F₁ = 225 N
and
(F₁ + F₂) - (F₁ - F₂) = 150 N - 300 N
2F₂ = -150 N
F₂ = -75 N
But F₁ and F₂ are magnitudes, so they must be positive! Also, it doesn't make sense that when the forces both point east, the mass accelerates less than it does when the forces work against each other. Probably one of the given accelerations are supposed to point west instead of east.
