2.3c Ex1 MJ15 P21 Q2 Ball Rebound Velocity Graph | AS Kinematics | Cambridge A Level 9702 Physics

Example 1 - 9702/21/M/J/15: (a) Define speed and velocity and use these definitions to explain why one of these quantities is a scalar and the other is a vector. #9702s15p21 #ASfreefallP2 #ASreboundP2 #Lv2 (b) A ball is released from rest and falls vertically. The ball hits the ground and rebounds vertically, as shown in Fig. 2.1. The variation with time t of the velocity v of the ball is shown in Fig. 2.2. Air resistance is negligible. (i) Without calculation, use Fig. 2.2 to describe the variation with time t of the velocity of the ball from t = 0 to t = 2.1 s. (ii) Calculate the acceleration of the ball after it rebounds from the ground. Show your working. (iii) Calculate, for the ball, from t = 0 to t = 2.1 s, the distance moved, and the displacement from the initial position (iv) On Fig. 2.3, sketch the variation with t of the speed of the ball. #ASphysicsGraphsP2 #Kinematics Chapter Playlist    • Ch2 Kinematics | CAIE 9702 AS Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
