Question

A moving body is covering distances which are proportional to the square of the time. Then the acceleration of the body is

• A. decreasing.
• B. constant but not zero.
• C. zero.
• D. increasing.

Hint:

When a body’s distance is proportional to the square of time, it means the body is undergoing uniformly accelerated motion, which implies constant acceleration.

Answer 1

The Correct Option is B

Step 1: Understanding the motion.
When the distance is proportional to the square of time, the motion is uniformly accelerated. The acceleration is constant because the body’s velocity increases at a constant rate.
Step 2: Conclusion.
Thus, the correct answer is (B) constant but not zero.
