Question

A ball dropped from a height of 4.10 m makes a perfectly elastic collision with the ground. Assuming no decrease in mechanical energy due to air resistance, complete the following. (a) Show that the ensuing motion is periodic. This answer has not been graded yet. (b) Determine the period of the motion. (c) is the motion simple harmonic? yes no Explain your answer.

Answer 1

a no energy If a ball is dropped from certain height he if the ground is perfectly eight elastic that means Will be lost during this motion & ball Will keep going down of going up at the same height from which it is dropped- Merce we can say that it will be a simple Harmonic motion - Home Here is the explanation for part ball motion ean of @ The dropping Uzom/s S = ut + 1/3 at? ho ottegt? 2x 4.10 0.836s t 11 ah g g. 8 also be some time for going up will also be t 0.8368 that means it is a continuasly Here it moves Periodic motion - 1.672 S 2 x 0.836 (b Time period T=at Time period T= 1.672 & e one complete oscillation -
