Hint: Don't forget the sign. a = S rad S² (b) How many revolutions do the tires make before coming to rest, given their initial angular velocity rad is 98 -? 3 revolutions (c) How long does the car take to stop completely? t = S(4) C s) In class, we calculated the minimum speed needed by a ball to maintain contact with the track at the top of a loop-the-loop. In this problem, I want you to calculate the minimum speed the ball must have at the bottom of the loop so it maintains contact at the top. Express your answer in terms of m (the mass of the ball), g, and R (the radius of the loop). v=211. A 450 g model rocket is on a cart that is rolling to the right at a speed of 4 m/s. The rocket engine, when it is fired, exerts a 6 N vertical thrust on the rocket. Your goal is to have the rocket pass through a small horizontal loop that is 22 m above the ground. At what horizontal distance left of the loop should you launch?
