You will be studying velocity and acceleration of a point undergoing uniform circular motion. This lab is based on the theory presented in Chapter 8 of the Knight (5th edition) textbook. Centripetal acceleration The point P is on a disc rotating counter-clockwise at constant angular speed with period T. Consider the instant when P is at its "right-most" position, and using the coordinate system shown (Fig. 1). C is the centre of the disc. Question 1: In terms of î and ĵ, what is the direction of the velocity of P? Show this direction in Fig 1. Question 2: In terms of î and ĵ, what is the direction of the acceleration of P? Show this direction in Fig 1. Question 3: What is the angular speed (w) of P, in terms of T?

Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude.
A runner taking part in the 200-m dash must run around the end of a track that has a circular arc with a radius of curvature of 30.0 m. The runner starts the race at a constant speed. If she completes the 200-m dash in 23.2s and rum at constant speed throughout the race, what is her centripetal acceleration as she runs the curved portion of the track?

A Bluray disc is 12 cm in diameter. When put into a player, it takes 30 seconds for the disc toaccelerate to its playing speed of 1500 revolutions per minute. After this time, it spins at a constantangular velocity. Explain why you did everything you did.a) Find the distance traveled by a point on the edge of the disc during the time it takes to reachits playing speed. b) Make plots of θ, ω and α for the first 60 seconds after the disc is put in the player. (Note thisis longer than the 30 seconds of acceleration.) You may assume it spins counterclockwise
