Explanation:

We have that

The wombats total displacement is

[tex]d_t=2100m[/tex]

The average velocity during that time is

[tex]v_{avg}=5m/s[/tex]

From the question we are told that:

initial Velocity [tex]V_1=5m/s[/tex]

initial Time [tex]T_1=4min=>240sec[/tex]

Final Velocity [tex]V_2=4m/s[/tex]

Final time  [tex]T_2=3min=>180sec[/tex]

a)

Generally, the equation for displacement is mathematically given by

d_t=(Initial +final) displacement

Where

initial displacement

[tex]d_1=V_1*t_1\\\\d_1=5*240[/tex]

[tex]d_1=1200m[/tex]

Final displacement

[tex]d_2=V_2*t_2\\\\d_2=5*180[/tex]

[tex]d_2=900m[/tex]

Therefore

[tex]d_t=(Initial +final) displacement[/tex]

[tex]d_t=1200+900[/tex]

[tex]d_t=2100m[/tex]

b)

Generally, the equation for Average velocity is mathematically given by

[tex]v_{avg}=\frac{d_t}{t_1+t_2}[/tex]

[tex]v_{avg}=\frac{2100m}{240+180}[/tex]

[tex]v_{avg}=5m/s[/tex]

in conclusion

The wombats total displacement is

[tex]d_t=2100m[/tex]

The average velocity during that time is

[tex]v_{avg}=5m/s[/tex]

Answer:

16.3333333 newtons

Explanation:

on earth it would 98 newtons

Answer:

The velocity is uniform (unchanging) from A to B

The velocity increases from O to A

The velocity is decreasing from B to C and C to D

Acceleration is zero from A to B because the velocity is constant

The object starts to move at O and stops at D

Answer:

500 N

Explanation:

Natural bouyency will keep the diver in the same place, no matter what the mass of gfs. This means if the diver is displacing with a weight of 500 N, the upthrust will also be 500 N.

Upthrust on the diver will be 500 N

It is the force exerted by a fluid on an object in upward direction .

Since , Upthrust = weight  of the liquid displaced by a submerged part of the body

so, Upthrust = mg         where m = mass of the body and

                                                  g = acceleration due to gravity

It is given weight of water displaced = 500 N

hence , Upthrust on the diver will be 500 N

(a) The length of the train is 54.6 m

(b)  The braking distance of the road train is 194.44 m

The given parameters:

acceleration of the car, a = 3.7 m/s²

initial velocity of the car, u = 30 m/s

final velocity of the car, v = 130 km/h = 36.11 m/s

To find:

The length of the train is the distance travelled by the car

The distance traveled by the car is calculated as:

[tex]v^2 = u^2 + 2as\\\\2as = v^2 - u^2\\\\s = \frac{ v^2 - u^2}{2a} \\\\where;\\\\s \ is \ the \ distance \ travelled \ by \ the \ car\\\\s = \frac{(36.11)^2 - (30)^2}{2\times 3.7} \\\\s = 54.585 \ m\\\\s \approx 54.6 \ m[/tex]

Thus, the length of the train is 54.6 m

(b) The braking distance of a road train travelling at 25 m s⁻¹

[tex]a = \frac{v_1^2}{2s_1} = \frac{v_2^2}{2s_2} \\\\Given;\\\\s_1 = 70 \ m\\\\v_1 = 15 \ m/s\\\\v_2 = 25 \ m/s\\\\s_2 = ?\\\\2s_2v_1^2 = 2s_1v_2^2\\\\s_2 = \frac{ 2s_1v_2^2}{2v_1^2} \\\\s_2 = \frac{s_1v_2^2}{v_1^2} \\\\s_2 = \frac{70\times 25^2}{15^2} \\\\s_2 = 194.44 \ m[/tex]

Thus, the braking distance of the road train is 194.44 m

Answer:

v=28.28m/s t=14.14s average velocity =2m/s

Explanation:

Starting at rest the initial velocity is 0 substituting that in the first equation of motion v=u+atgives the final velocity but we first have to determine the time using the third equation of motion which is s=ut+1/2at^2 and then do the substitution. Average velocity is the determined by adding the initial and final velocity then divide it by 2

Answer:

D. 16 Kgm/s

Explanation:

Let the momentum of the two balls be A and B respectively.

Momentum A = 16 kgm/s

Momentum B = 0 kgm/s (since the ball is at rest).

Total momentum = A + B

Total momentum = 16 + 0

Total momentum = 16 Kgm/s

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

Answer:

It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth's oblateness. ... The measured value is larger because the earth's density is not uniform but increases toward the center.

Answer:

as explained that poles have more gravitational

force (9.83m/s^2) as the poles of earth is nearer to the center because it is flat at poles

but certainly at equator is having less gravitational force (9.78m/s^2) as it is Farr from centre of earth because it is bulgded at equator.

hence, poles have more gravitational force as co.pared to that of equator.
