and direction. -6) j+(4) 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=0 as a product What is the velocity vector? v(t)=(3) i+ (16t) j + (4) k What is the acceleration vector? i+ a(t)=(0) + (16) j + (0) k Write the velocity vector at t=0 as a product of the speed and direction. v(0) (5) (3) + (0) + (4) k] (Type exact answers, using radicals as needed.)
