a particle p starts from a point a with velocity 4m/s.if it is moving along a strait line ab with an acceleration of -1.5t^2 at a time t seconds, find acceleration,diplacment after ten seconds,velocity

Answer 1

acceleration is not in t^2 units.
If you mean a = -1.5 m/s^2, then

v = 4-1.5t
s = 4t - .75t^2

plug in t=10.
