f3 h} Perform appropriate calculations to determine whether the collision is elastic. State your conclusion. 3. A billiard cue ball with a mass of 0.60 kg and an eight ball with a mass of 0.55 kg roll toward each other. The cue ball has a velocity of 3.0 m/s at 0" and the eight ball has a velocity of 2.0 m/s at 90%. After the collision, the cue ball moves off at a velocity of 2.0 m/s at 40. Include vector diagrams in your answer to show how you determined the missing values for both the eight ball and the cur ball. m =0.60 kg before after V = 3.0 m/s P'e Pe m =0.55 kg V = 2.0 m/s Ps a) Determine the velocity of the eight ball. /66. A new communications satellite launches into space. The rocket carrying the satellite has a mass of 2.04 x 10 kg. The engines expel 3.7 x 103 kg of exhaust gas during the first second of liftoff giving the rocket a velocity of 5.7 m/s [up]. At what velocity is the exhaust gas leaving the rocket engines? Ignore the change is mass due to the fuel being consumed. The exhaust gas needed to counteract the force of gravity is already been accounted for and should not be part of this calculation. Show all calculations.1. A car with a mass of 1400 kg is westbound at 50 km/h. It collides at an intersection with a northbound truck having a mass of 2000 kg and travelling at 40 km/h. What is the initial common velocity of the car and truck immediately after the collision if they have an inelastic collision? For this question, a diagram is drawn for you. (You will find that drawing such a diagram will often be useful in solving two dimensional problems.) Z Pear pouiqwood young S /5 81A police car with a mass of 1400 kg is headed west at 50 kah when it has an inelastic collision with a southbound ZUDD-kg ambulance. The wreckage ended up travelling at 45 kmx'h at 236\". a] What was the initial speed of the ambulance? Include a vector diagram with your answer.
