Starting from rest a particle moves in a straight line with acceleration
`a = (25 - t^(2))^(1//2) m//s^(2) " for " 0 le t le 5s`
`a = (3pi)/(8) m//s^(2) " for " t gt 5s`
The velocity of particle at `t = 7 s` is:

A particle starts from rest at t=0 and moves along a straight line with a variable acceleration given by a (t)=(3t+1)ms^(-2) ,where t],[ is in seconds.The velocity of the particle at t=4s is

Starting from rest, acceleration of a particle is a = 2t (t-1) . The velocity of the particle at t = 5s is

A particle starts from rest at t=0 and moves in a straight line with an acceleration as shown below. The velocity of the particle at t=3 s is

A particle starts from rest at t=0 and moves in a straight line with an acceleration as shown below. The velocity of the particle at t=3 s is

A particle moves in a straight line with an acceleration a m/s^(2) at time t seconds,where a=-(1)/(t^(2)) .When t=1 the particle has a velocity of 3m/s .If the velocity of the particle at t=4s is (9)/(n)ms^(-1) The value of n is

A particle, initially at rest, starts moving in a straight line with an acceleration a=6t+4 m//s^(2) . The distance covered by it in 3 s is
