Question

If in case of a motion, displacement is directly proportional to the square of time elapsed, what do you think about its (A) velocity (B) acceleration?

• A. Velocity varies inversely with time and acceleration is a constant.
• B. Velocity proportional to square of time and acceleration is constant.
• C. Both velocity and acceleration are proportional to square of time.
• D. Velocity varies linearly with time whereas acceleration is constant.

Answer 1

The correct option is D

Velocity varies linearly with time whereas acceleration is constant.
