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.
