1. A particle travels in space according to the function: 7 = 2tî + (5t² - t)ĵ + 3t²k and its velocity is: = 2 + (10t - 1)j + 6tk a. At t = 2, what is the position of the particle? b. At t = 2, what is the velocity of the particle? c. At t = 2, what is the cross product between the velocity and the position? d. At t = 2, what is the dot product between the velocity and the position?
