Question

The acceleration of a particle is zero at $t=0$. Then choose the incorrect option :-

• A. Its velocity must be constant
• B. The speed at t = 0 may be zero
• C. If the acceleration is zero from t = 0 to t = 5s, the speed is constant in this interval
• D. If the speed is zero from t = 0 to t = 5s, the acceleration is also zero in this interval

Answer 1

Answer: (A)

Correct answer is (a) Its velocity must be constant
