Q1. 1) An 865 kg drag race car accelerates from rest to 111 km/h in 0.749 s. What change in momentum does the force produce?
Respond in units of kg • m/s
2) what average force is exerted on the car? Response in units of N
Q2. A 75 g, 31 cm long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 12 g ball of clay travelling horizontally at 2.1 m/s hits and sticks to a very bottom tip of the rod.
To what maximum angle, measured from vertical, does rod (with the attached ball of clay) rotate?
