Question

Can i get help with these problems

A glob of very soft clay is dropped from above onto a digital scale. The clay sticks to the scale on impact. A graph
of the clay's velocity vs. time, velay (t), is given, with the upward direction defined as positive.
The experiment is then repeated, but instead of using the clay glob, a superball with identical mass is dropped
from the same height onto the scale.
Both the clay and the superball hit the scale 2.9 s after they are dropped. Assume that the duration of the
collision is the same in both cases and the force exerted by the scale on the clay and the force exerted by the
scale on the superball are constant.

Part A
Sketch the graph of the superball's velocity vs. time, vhall (t), from the instant it is dropped (t = 0 s) until it bounces to its maximum height (t = 6 s). Assume that the superball undergoes an elastic collision with the scale, and that the scale's recoil velocity is negligible.
The light colored graph already present in the answer window is vdlay (t).
