Question: The equation r ( t ) = ( t ) i + ( 3 2 t - 1 6 t 2 ) j is the

The equation r(t)=(t)i+(32t-16t2)j is the position of a particle in space at time t. Find the angle between the velocity and acceleration vectors at time t=0.
The angle between the velocity and acceleration vectors at time t=0 is radians.
(Type an exact answer, using as needed.)
