If the distance `s` travelled by a particle in time `t` is given by `s=t^2-2t+5`, then its acceleration is

If the distance s travelled by a particle in time t is s=a sin t +b cos 2t , then the acceleration at t=0 is

If the distance s travelled by a particle in time t is s=a sin t +b cos 2t , then the acceleration at t=0 is: a) a b) -a c) 4a d) -4b

If the distance s travelled by a body in time t is given by s = a/t + bt^2 then the acceleration equals

The distance s moved by a particle in time t is given by s=t^(3)-6t^(2)+6t+8 . When the acceleration is zero, the velocity is ………..
