A ball of mass m and speed v travels horizontally, hits a wall, and rebounds. Another ball of the same mass and traveling at the same speed hits the wall and sticks to it. Which ball has a greater change in momentum as a result of the collision? Create a momentum bar chart to explain your answer.

A green car with mass 1200 kg is travelling east at 40 m/s. Simultaneously, a yellow car with mass 1500 kg is travelling north at 30 m/s.

What is the momentum of each car before the collision? c. What is the magnitude of the momentum of the two combined cars after the collision? d. What is the speed (magnitude) of the two cars after the collision? e. What is the direction of the motion of the cars after the collison?

*Problem 2: т An object is initially moving in the positive y-hat direction with a speed of 1 The object then explodes into three S m pieces. Piece 1 has a mass of 0.5 kg and moves with a velocity of 2£ + 3ŷ. Piece 2 has a mass of 0.35 kg and m moves with a velocity of -3£ + 1ŷ. Piece 3 has a mass of 0.15 kg. a) Draw a picture of the situation. b) Apply conservation of momentum to this problem. c) Find the velocity of piece 3. (Answer: 0.33£ – 5.7ŷ)

Two objects, A and B, with masses 3.2 kg and 1.8 kg, move in a frictionless horizontal surface. Object A moves to the right at a constant speed of 5.1 m/s while object B moves to the right at a constant speed of 1.4 m/s.  They collide and stick together. a) Find the total kinetic energy of the system after the collision. b) Is the kinetic energy of the system conserved?  Explain.

Three balls A, B, and C with masses 0.0500 kg, 0.0700 kg, and 0.0900 kg, respectively, are moving along the xy-plane and approaching the origin as shown in the figure below. Ignore friction. The initial velocities of balls A and B are shown in the figure. Suppose all three balls arrive the origin at the same time and stick together after the collision. a. What must be the x- and y-components of the initial velocity of ball C in order for the three balls to move along the +x-axis at 1.00 m/s after the collision?

Imagine a collision between two balls: ball A has an initial momentum p of 2 kg-m/s to the right, and ball B is stationary before the collision. B has a mass of 1 kg. After the collision, the velocity of A is 2 m/s to the left and that of B is 3 m/s to the right. What are the mass and initial velocity of ball A? a) The mass of ball A is 5 kg, and its velocity 2 m/s. b) The mass of ball A is 1 kg, and its velocity 3 m/s. c) The mass of ball A is 2 kg, and its velocity 4 m/s. d) The mass of ball A is 0.5 kg, and its velocity 4 m/s.

A hockey player with mass 87.7 kg is skating 7.2 m/s towards the east side of the hockey rink. A second hockey player with a mass of 105.2 kg is skating 8.1 m/s towards the north side of the hockey rink. The two hockey players collide and grab onto each other so they move together after the collision. What is the magnitude of the velocity of the hockey players after the collision? m/s What is the direction, give an angle north of east, of their final velocity after the collision? Degrees north of east

Two blobs of clay are fired at each other. Blob 1 is moving to the right, while Blob 2 is moving to the left. The mass of Blob 1 is larger, but Blob 2 has a higher speed. After both blobs collide and stick together, they move to the left. Which blob had more momentum before the collision? Explain your reasoning.

You drop a steel ball and a clay ball, both of the same mass, from the same distance. The steel ball strikes the ground and rebounds with almost the same speed. The clay ball strikes the ground and sticks. Assume the collisions occur over roughly the same amount of time. Which ball exerted a greater force on the ground? Select the correct answer with the best explanation. A. The two exert the same force. Since they collide with the same initial momentum, they will exert thesame force.B. The clay ball exerts the greater force. Since it starts with some momentum and ends with no momen- tum, it undergoes a greater change in momentum than the steel ball, which rebounds with the same momentum (no change).C. The clay ball exerts the greater force. All of its energy is transferred to the floor, whereas the steelball rebounds with the same kinetic energy, doing no work on the floor.D. The steel ball exerts the greater force. Since it starts with some momentum and it reverses the direction of…
