The displacement 's' of a moving particle at a time H is given by s=5+20t-2t^(2) .Calculate its acceleration when the velocity is zero.

The displacement s of a moving particle at a time t is given by s=5+20t-2t^(2) . Find its acceleration when the velocity is zero.

If the displacement of a moving particle is given by s=5 + 20 t-2t^(2), then acceleration when velocity is zero, is

The displacement s of a particle at a time t is given bys =t^(3)-4t^(2)-5t. Find its velocity and acceleration at t=2 .

The displacement of a particle in time t is given by s=2t^2-3t+1 . The acceleration is

The displacement of a particle at time t is given by s= 2t^(3) -5t^(2)+ 4t-3 . The time when the acceleration is 14ft/ sec^(2) is

The displacement s of a particle at time t is given by s=alpha sin omegat+beta cos omegat then acceleration at time t is

5.The displacement s of a particle at a time t is given by s=2t-5t+4t-3, find (i) the time when the acceleration is 14 ft/sec (ii) the velocity and the displacement at that time.

The displacement 's ' of a particle at time 't' is given by s = t^3 - 4t^2 - 5t . Find its velocity and acceleration at ime t= 2 seconds .Also, find t when its acceleration is zero .

The displacement of a particle at time t is given by s= 2t^(3) -5t^(2)+ 4t-3 . Find the velocity when t = 2 sec.

Displacement s of a particle at time t is expressed as s=(1)/(2)t^(3)-6t. Find the acceleration at the time when the velocity vanishes (i.e.,velocity tends to zero).
