find the velocity vector, find the eccelartion vector, find the speed and direction

The equation r(t) = (2t + 3) i + (t - 9) j+ (t) k is the position of a particle in space at time t. Find the particle's velocity and acceleration vectors. Then write the particle's velocity at t= 1 as a product of its speed and
direction.
