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 v3.1ģ. 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.

Complete the momentum conservation diagram. 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. Suppose that the golf ball was in contact with the floor for 4.0 x 10-4s.Transcribed image text: Name Date Pd Impulsive Force Model Worksheet 3: Conservation of Momentum I 1. What will be the change in momentum, (p) from the instant before the ball collides with the floor until the instant after it rebounds from the floor? (Illustrate with a vector diagram.)Į. What will the instantaneous momentum of the golf ball be immediately before it strikes the floor? d. Determine the time required for the ball to reach the floor. Construct a motion map for the golf ball from the time it is dropped until it reaches its highest point of rebound. Perfectly elastic collision with the floor.Ī. A golf ball that weighs 0.45 N is dropped from a height of 1.0 m. For how much time must the engine burn during the launch in order to reach this speed?ĥ. A rocket, weighing 4.36 x 104N, has an engine that provides an upward force of 1.2 x 105N. Modeling Instruction - AMTA 2013 2 U9 Momentum - ws 2 v3.1Ĥ. How large is the force the ball exerts on the bat? Explain. What is the final velocity of the ball? d. When the batter hits the ball, a net force of 1150 N, opposite to the direction of the ball's initial motion, acts on the ball for 9.0 x 10-3 s during the hit. If the initial speed of the baseball is v = 0.0 m/s, what will its speed be when it leaves the pitcher's hand? c. What is the magnitude of the change in momentum of the ball?ī. While being thrown, a net force of 132 N acts on a baseball (mass = 140 g) for a period of 4.5 x 10-2 sec. The following questions refer to the motion of a baseball.Ī. Justify your answer.ī) Find the value of the ratio of kinetic energy C to kinetic energy D. Object C has twice the velocity of object D.Ī) Find the value of the ratio of momentum C to momentum D.

Two other objects, C and D, have identical masses. Justify your answer.ī) Find the value of the ratio of kinetic energy A to kinetic energy B. Object A has 3 times the mass of object B.Ī) Find the value of the ratio of momentum A to momentum B. Two objects, A & B, have identical velocities.
