Question 1

The position function of a particle is given by r(t) = t2, 5t, t2 - 16t. When is the speed a minimum?
◦ t = 4
◦ t = 3
◦ t = 1
◦ t = 2
◦ t = 5

Question 2

The position of a particle at time t is given by r =  (cos t) i + (sin t) j  +  t k.  Find the speed and the magnitude  of the acceleration at any time  t.  Describe the motion.
◦ = ;   = ;   path is a circle
◦ = ;   = 1;   path is a circle
◦ = ;   = 1;   path is a circular helix
◦ = ;   = ;   path is a circular helix
◦ = ;   = 2;   path is a circular helix
