A completely inelastic collision occurs between two balls of wet putty that move directly toward each other along a vertical axis. Just before the collision, one ball, of mass 3.9 kg, is moving upward at 20 m/s and the other ball, of mass 1.4 kg, is moving downward at 13 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)

I.  A lump of clay (m = 3.01 kg) is thrown towards a wall at speed v = 3.15 m/s.  The lump sticks to the wall.  (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   II.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 3.15 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic energy lost during this collision.   III.  Same lump is thrown towards the same wall, but this time it bounces off the wall at speed of 2.24 m/s. (a) What kind of collision is it?  Is momentum conserved during this collision?  Why or why not? (b) Calculate the impulse imparted on the lump by the wall. (c) Calculate percent of initial kinetic…

Two balls of masses m, = 3.90 kg and m, = 1.60 kg move along the x axis. The initial velocities of the balls are VLj = 28.0 m/s and v2j = -12.0 m/s. The balls collide in a head-on elastic collision. Find the velocities of the balls after the collision. (a) First ball: V1,f m/s (b) Second ball:. V2,f = m/s

On a horizontal frictionless table, masses A and B (3 kg, 5 kg) slide to the right and left, respectively. They have speeds of 3 m/s and 1 m/s, respectively. The two masses collide, and bounce off each other. After the collision, they travel in opposite directions at speeds of 1.5 m/s and 1.700 m/s, respectively. (Note:In this problem, please use + dir = right, - dir = left, to indicate direction.) a.) Calculate A's momentum: before collision: kg-m/s after collision: kg-m/s Make sure you understand why it is NOT conserved. b.) Calculate B's momentum: before collision: kg-m/s after collision: kg-m/s Make sure you understand why it is NOT conserved. c.) Calculate the A+B system's momentum: before collision: kg-m/s after collision: kg-m/s Make sure you understand why it IS conserved. d.) Calculate the kinetic energy of the A+B system: before collision: after collision: J What kind of collision is this v ---Select--- elastic somewhat inelastic Submit Answer completely inelastic

Two identical 0.5 kg pucks collide on a frictionless, level surface. Puck #1 is initially moving along the x-axis at 3 m/s (or, 3i m/s) and puck #2 is initially at rest. After the collision puck #1 has a velocity given by (0.5i + 1j) m/s. a) Find puck #2’s final velocity. b) How much kinetic energy is lost in the collision?

A 65.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped at him at a velocity of 28.0 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities (in m/s) be in this case? (Assume the original direction of the ice puck toward the goalie is in the positive direction. Indicate the direction with the sign of your answer.) puck m/s goalie m/s

A young 44-kg ice hockey goalie, originally at rest, deflects a 0.145-kg hockey puck slapped at him at a speed of 37 m/s. In this problem, take the original direction of the puck as positive. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would the final velocity of the puck, in meters per second, be in this case?  Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would the final velocity, in meters per second, of the goalie be in this case?
