![]() ![]() ![]() When a 150 kg cannon and cart recoils at 1.5 m/s, at what velocity would a 10.0 kg cannonball leave the cannon a. Old cannons were built on wheeled carts, both to facilitate moving the cannon and to allow the cannon to recoil when fired. When you increase velocity it increases momentum. Impulsive Force Model Worksheet 4: Conservation of Momentum II 1. Question: When starting a heavy train, why will train engineers sometimes back up, stop, and then proceed forward? (This technique is called “bunching slack”.)Īnswer: The objective is to gain momentum using force you used before. 04 U9 ws 2.pdf - Name Date Pd Impulsive Force Model. Two objects, A & B, have identical velocities. Question: Nylon ropes stretch considerably under tension and are favored by mountain climbers because the ropes Name Date Pd Impulsive Force Model Worksheet 2: Impulsive Forces and Momentum 1. So if it takes more time to hit something then it would hurt less based on force being less. Question: Why are padded dashboards safer than hard dashboards in automobilesĪnswer: In terms of impulse, FT=P, the more F the less time, since they’re inverse. Mass is again inverse to acceleration meaning the less mass the greater the acceleration. Question: Which vehicle will experience the greater acceleration?Īnswer: The Beetle because F/M=a. P/M=V, mass is inverse to velocity so the less mass, the faster. Impulsive force model worksheet 3 conservation of momentum 1 answer key By the end of this section you will be able to do the following. Question: Which vehicle will experience the greater change in momentum? Justify your answer.Īnswer: The Beetle because it has less mass which means it goes faster. The cars will both exert an action/reaction force onto each other. Which vehicle will experience the greater force of impact? Justify your answer.Īnswer: The force of impact will be the same for both based on Newton’s 3rd Law- action reaction. ![]() Question: A Hummer and a VW Beetle traveling at equal speeds have a head-on collision. The ball that bounces has a GREATER change in momentum being that the numerical value is larger. Question: Which has the greater change in momentum, a 50 gram clay ball that strikes a wall at 1 m/s and sticks or a 50 gram superball that strikes a wall at 1 m/s and bounces away from the wall at 8.0 m/s? Explain? Newton’s first law says that there’s not enough friction to stop/turn you. Will you roll backwards if you go through the motions of throwing the ball, but hold on to it instead? Explain your reasoning.Īnswer: You’ll go forward because your roller skates stay in motion. Question: If you throw a ball horizontally while standing on roller skates, you roll backwards. ![]()
