Directions: Answer the following questions concerning the conservation of momentum using the equations below. Show all of you work to receive credit. 1. When these two freight cars of different mass collide and couple, what will be their resultant velocity? 2. A 2 kg blob of putty moving at 4 m/s slams into a 6 kg blob of putty at rest.
Practice with Conservation of Momentum - Answers Conceptual Questions 1. Why is momentum conserved for ALL collision, regardless of whether they are elastic or not? Newton’s 3rd Law says that each object feels the same force, but in opposite directions. By extension, they
Determine the mass of the empty freight car. What are the initial and final kinetic energies of the system and what percent of the energy was lost (energy lost / initial energy). A 6–kg mass moving at 10 m/s has a head-on collision with a 4–kg mass that is initially at rest. Following the collision, the 6 kg mass moves at a speed of 2 m/s.
Physics P Worksheet 6-8: Conservation of Momentum Worksheet 6-8 Conservation of Momentum 1. Represent the momentum of each object with a velocity-mass bar graph. a. A 1000 kg car travels to the right at 22 m/s. b. A 10 000 kg airplane has an instantaneous velocity of 2 m/s while accelerating to the left at 25 m/s2. c.
2015年2月26日 · Law of Conservation of Momentum Worksheet Equations Needed: p = m∙v Momentum = Mass ∙ Velocity pi = p f Initial Momentum = Final Momentum m1∙v1i + m2∙v2i = m 1∙v1f + m2∙v2f 1. A 1.27 kg toy cannon is loaded with a 54 gram tennis ball and placed on the floor. If the cannon recoils with a speed of 7.8 m/s, what is the speed of the ball?
Worksheet: Conservation of Momentum p before = p after net momentum before = net momentum after (m 1` v 1 + m 2` v 2) before = (m total` v) after 1. When these two freight cars of different mass collide and couple, what will be their resultant velocity? 2. A 2 kg blob of putty moving at 4 m/s slams into a 6 kg blob of putty at rest.
In order to apply the law of conservation of momentum, what should the system be? One ball or both billiard balls? A hockey puck of mass 0.17 kg and velocity 5 m/s is caught by a 0.5 kg mitten laying on the ice.
