Missy’s favorite ride at the Topsfield Fair is the rotor. This is a circular ride (with a radius of 4.0m) where people stand up against the wall and it spins around and the floor drops out. The ride takes 2.0s to make one full revolution a. What is providing the centripetal force on Missy? b. What is Missy’s linear velocity? c. What is Missy’s centripetal acceleration on the ride?

. A 3.0kg cannon ball is shot from a cannon at a speed of 20m/s. The cannon is oriented50 degrees above the horizontal and the cannon’s barrel is 8.0m above the ground. Youwant to position a mat that will catch the cannon ball.a. Determine how much time the cannon ball will spend in flight.b. Draw a force diagram for three points during the cannon ball’s flight (1) while itis being shot from the cannon, (2) when it is at its maximum height, and (3) whenit is half-way between the maximum height and the mat.c. Determine the horizontal distance from the end of the barrel where you shouldplace the mat so that it will catch the ball.d. How fast is the cannon ball moving just before it hits the mat?
