Chapter: Momentum and Collisions 5) If mass of the Class 5 yellow truck is 8,845 Kg and Velocity is 15.64 m/s (35 m/h). Find momentum of the truck? 6) In a laboratory experiment (see figure) a 200g air track glider and a 400 g air track glider are pushed toward each other. From opposite ends of Before: the track. The gliders have Velcro tabs on their m, = 200 g m, = 400 g fronts so that they will stick together when they collide. The 400g glider is pushed with an initial speed of - 4.5m/s. The combined velocity after collision is - 0.5 m/s. a) Derive the equation for the initial velocity for After: 200 g glider? Assume momentum is conserved. m, + m, (v.), = -0.50 m/s 2 b) Compute the velocity of the 200 g glider
