A body experiences acceleration "a" given by the expression [itex]a=At-Bt^2[/itex] where A and B are constants and t is time. If at time t=0, the body has zero displacement and velocity, at what next value of time does the body again have zero displacement?

2. Relevant equations

a is in m/s^2

v is in m/s

d is in m

3. The attempt at a solution

when t=0

displacement

[itex]at^2 = d = 0 = At^3 - Bt^4[/itex]

velocity

[itex]at = v = 0 = At^2 - Bt^3[/itex]
