Answer:
(d) I and III
Explanation:
Motion of the 1st light ball
I. Since the heavier starts with an initial velocity v0, and both balls end up traveling the same distance s. From the 2 motion equation above we can conclude that their time must be different
II. Both balls are affected by the same gravitational acceleration g
III. Velocity before the impact of the light ball
And the heavy ball
Since they have the same acceleration g and distance s. But the heavy ball has an initial push. It would end up with a larger speed.
When soccer players run they are using friction to propell themselves
Work = Force x displacement
Force= 20N
Displacement= 0.75m
W= 20(0.75)
W= 15 Nm
