The velocity of a particle is zero at t=0

Options

A. The acceleration at t = 0 must be zero
B. The acceleration at t=0 may be zero
C. If the acceleration is zero from t = 0 to t = 10s, the speed is also zero in this interval
D. If the speed is zero from t = 0 to t = 10s the acceleration is also zero in this interval

Answer

B, C, D

Explanation

At t= 0 , acceleration may or may not be zero.
t=0 , speed is zero . So , without acceleration , particle remains at rest .
