Question: The equation r ( t ) = ( 8 t + 5 ) i + ( 4 t 2 - 3 ) j + (

The equation r(t)=(8t+5)i+(4t2-3)j+(6t)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 of its speed and direction.
The equation r ( t ) = ( 8 t + 5 ) i + ( 4 t 2 -
