JEE PYQ: Motion In One Dimension Question 14

Question 14 - 2020 (04 Sep Shift 1)

A Tennis ball is released from a height $h$ and after freely falling on a wooden floor it rebounds and reaches height $\frac{h}{2}$. The velocity versus height of the ball during its motion may be represented graphically by: (graph are drawn schematically and on not to scale)

(1) v vs h(v) — elliptical loop going right for fall and left for rise, symmetric

(2) v vs h(v) — two separate curves, fall and rise

(3) v vs h(v) — single loop, asymmetric with h/2 marked

(4) v vs h(v) — asymmetric loop with h and h/2 marked
