Question

9. A ball is thrown vertically up (taken as +Z-axis) from the
ground. The correct momentum - height (p-h) diagram is:
ТР
​

Answer 1

Answer: (4)

Go through the attachment.

1. during upward motion, velocity is positive, so the momentum is also positive.

2. during download motion, velocity is negative, so the momentum is also negative.

3. 3rd equation depicts the relation between velocity and displacement (or, say height). so, there is parabolic relationship between V and h.

these points are followed by graph-(4) ...

hope, it may help you.
