3.4b Ex3 MJ09 P2 Q2 Ball Collision Graph | AS Dynamics | Cambridge A Level 9702 Physics

Example 3 - 9702/2/M/J/09: A ball B of mass 1.2 kg travelling at constant velocity collides head-on with a stationary ball S of mass 3.6 kg, as shown in Fig. 2.1. Frictional forces are negligible. The variation with time t of the velocity v of ball B before, during and after colliding with ball S is shown in Fig. 2.2. #9702s09p2 #AScollisionsP2 #Lv2 (a) State the significance of positive and negative values for v in Fig. 2.2. (b) Use Fig. 2.2 to determine, for ball B during the collision with ball S, (i) the change in momentum of ball B, (ii) the magnitude of the force acting on ball B. (c) Calculate the speed of ball S after the collision. (d) Using your answer in (c) and information from Fig. 2.2, deduce quantitatively whether the collision is elastic or inelastic. #Dynamics Chapter Playlist    • Ch3 Dynamics | CAIE 9702 AS Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
