1 of 9 Situation 1 - Hard Surface Situation 2 - Soft Surface m m V V 45 45 (0,0) 45 (0,0) 30 - X V2 F A ball of mass m and velocity v contacts a hard surface at a 45 angle and bounces off the surface also at a 45" angle and at speed v, as shown in situation 1. Also shown is the force vector F representing the force exerted by the surface on the ball. Situation 2 shows the same ball moving with the same velocity and contacts a soft surface. The time of contact is greater with the soft surface than the hard surface. The ball bounces off the soft surface at an angle of 30" and with speed v2
