A particle is moving so that its displacement is given as 
meter. Its velocity at the instant when its acceleration is zero will be
Text Solution
Verified by ExpertsThe correct answer is:
D
S = t 3 – 6t 2 + 3t + 4
V = 
= 3t 2 – 12t + 3
a = 
= 6t – 12 = 0
t = 2 sec
v = 3(b) 2 – 12 × 2 + 3 = 2 – 24 + 3 = –9m/s
