So if it takes more time to hit something then it would hurt less based on force being less. In a railroad yard a train is being assembled. Find the speed of the melon as it flies off the performer's head.Conservation of momentum 1 worksheet answers. event: initial final mass/object/velocity mass/object/velocity 0 b. Draw a momentum conservation diagram for the stunt. The arrow passes through the melon and emerges with a speed of 18 m/s. An archer shoots a 50 g arrow at the melon with a speed of 30 m/s. A 2 kg melon is balanced on a circus performer's head. Calculate the impulse that each girl imparts to the other. event: initial final mass/object/velocity mass/object/velocity 0 0 + b. Show the effect of the push on both girls with a momentum conservation diagram. The taller girl pushes the shorter girl so that the shorter girl rolls away at a speed of 10 m/s.
Two girls with masses of 50 kg and 70 kg are at rest on frictionless in-line skates. What was the velocity of the cart after the boy jumped? Modeling Instruction - AMTA 2013 2 U9 Momentum - ws 3 v3.1 5. How large an impulse did the boy give to the cart? d. event: initial final mass/object/velocity mass/object/velocity 0 + 0 b. Complete the momentum conservation diagram. A 70 kg boy, riding in the cart, jumps off so that he hits the floor with zero velocity. A 50 kg cart is moving across a frictionless floor at 2.0 m/s. How much force did the racket exert on the ball? 4. event: initial final mass/object/velocity mass/object/velocity 0 + b. Use a momentum conservation diagram to show the change in momentum of the ball. A tennis player returns a 30 m/s serve straight back at 25 m/s, after making contact with the ball for 0.50 s. CModeling Instruction - AMTA 2013 U9 Momentum-Ws 3 v3.1 3.
Find the speed with which the astronaut moves off into space. event: initial final mass/object/velocity mass/object/velocity 0 Momentum conservation equation: b. By pushing the tank away with a speed of 2.0 m/s, the astronaut recoils in the opposite direction. An astronaut of mass 80 kg carries an empty oxygen tank of mass 10 kg. event: initial final mass/object/velocity mass/object/velocity + 0 Momentum conservation equation: b. Each of the boxcars has a mass of 9000 kg when empty, and the loaded car contains 55,000 kg of lumber. An empty boxcar, coasting at 3 m/s, strikes a loaded car that is stationary, and the cars couple together. In a railroad yard, a train is being assembled.
