The velocity of particle is zero at t=o. a)acc. at t = 0 muct be zer. b)acc. at t = 0 may be zero. c) if acc. is zero from t = o to t = 10 s, the speed is also zero in this interval.. d) if speed is zero from t= 0 to t = 10s, the acc.is zero in this interval........Justify your ANSWERS.

the answers are b c d

 

a is incorrect because an accelerated particle may have zero velocity at some point of time like a stone thrown up have zero velocity at highest point despite being constantly accelerated.

b is correct because it s possible that a particle dont experience any force and stay at rest.

c is correct because without any acceleration speed of any particle canot change.

d is correct because there is no change in speed or velocity so there was no acc.
