Question
Transcribed Image Text:A uniform solid ball has a mass of 20 g and a radius of 5
cm. It rests on a horizontal surface. A sharp force is applied
to the ball in the horizontal direction 9 cm above the
surface. The force rises linearly from 0 to a peak value of
40,000 N in s and then decreases linearly to 0 in another s.
(The moment of inertia for a solid ball is)
a) What is the velocity of the ball after the impact?
b) What is the angular velocity of the ball after the impact?
c) What is the velocity of the ball when it begins to roll
without sliding. (This means).
d) For how long does the ball slide on the surface given the
coefficient of kinetic friction
