Questions
A particle is moving along x-axis whose acceleration is given by a = 3x – 4, where x is the location of particle. At t = 0, the particle is at rest at
detailed solution
Correct option is A
At t = 0, V = 0, x = 43 a = 4×33−4=0 As velocity and acceleration both are zero at t = 0, so it will remain at rest and hence distance travelled in any time interval would be zero.Talk to our academic expert!
