Question

Which of the following is/are example/s of uniform motion? I- A ball falling to the groundII- A ball thrown up from the ground (A) Only I (C) Both I and II (B) Only II (D) Neither I nor II​

Answer 1

Explanation:

SOLUTION

At a particular time say s

Particle has velocity

and thus momentum

Also, displacement is 0

At time ,

Particle reaches maximum height with displacement

Here, velocity

Now,

when particle comes back to its initial position,

Velocity is reversed i.e.

and thus,

momentum,

So, we get graph corresponding Option D.
