Acceleration = (force) / (mass)
If there is no friction . . .
Acceleration = (200N) / (50 kg) = 4m/s²
Change in speed = (acceleration) x (time) = (4 m/s²) x (10 sec) = 40 m/s
<em>Final speed = (speed of the cart before the force began) + (40 m/s more)</em>
(That's about <em><u>89 mph faster</u></em> than the cart was moving before the force started.)
9.8m/s^2, i’m not sure what you are asking
Answer:
12 years
Explanation:
12 years is correct because how long is Jupiter one year is 12 years
The time spent in the air by the ball at the given momentum is 6.43 s.
The given parameters;
- <em>momentum of the ball, P = 0.9 kgm/s</em>
- <em>weight of the ball, W = 0.14 N</em>
The impulse experienced by the ball is calculated as follows;

where;
is impulse
is change in momentum
The time of motion of the ball is calculated as follows;

Thus, the time spent in the air by the ball at the given momentum is 6.43 s.

Let’s use *queue dramatic voice* THE GREAT LAW OF THE CONSERVATION OF MOMENTUM!!!!!
m1v1i + m2v2i = m1v1f + m2v2f
m1v1i - m1v1f = m2(v2f - v2i)
m2 = (m1v1i - m1v1f) / (v2f - v2i)
m2 = [(0.15)(15) - (0.15)(1.2)] / (13 - -22)
Henceforth, my good sire, the mass indeed works out to a fine approximate value of:
m = 0.06 kg
That’s a pretty small tennis ball!
