Now the racquet ball is moving straight toward the wall at a velocity of v = 17.3 m/s. The ball makes an inelastic collision
with the solid wall and leaves the wall in the opposite direction at vf = -10.9 m/s. The ball exerts the same average force on
the ball as before.
What is the magnitude of the change in momentum of the racquet ball?

6) What is the change in kinetic energy of the racquet ball?
J Submit

A racquet ball with mass m = 0.23 kg is moving toward the wall at v = 17.3 m/s and at an angle of 0 = 33° with respect to
the horizontal. The ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle
with respect to the horizontal. The ball is in contact with the wall for t = 0.066 s.

1. A firecracker travels straight up at 75.0m/s and explodes into two pieces. The smaller piece carries one third of the firecracker's mass and shoots off horizontally at 48.0m/s west. Determine the speed and direction of the other piece directly after the explosion. 2. Three blocks slide on a smooth surface. Initially, the first block (m1=1.0kg) moves at 3.0m/s to the right, the second block (m2=2.0kg) is at rest, and the third block (m3=3.0kg) moves to the left at 0.50m/s. First, m1 collides elastically with m2 and recoils to the left. Afterwards, m2 and m3 collide and stick. Calculate, a. the velocities of m1 and m2 after the first collision. b. the velocity of m2 and m3 after the second collision.
5. A vessel at rest at the origin of an xy coordinate system explodes into three pieces. Just after the explosion, one piece, of mass m, moves with velocity (−70 m/s) and a second piece, also of mass m, moves with velocity (−70 m/s). The third piece has mass 3m. (a) Just after the explosion, what is the magnitude of the velocity of the third piece? --------m/s(b) What is the direction of the velocity of the third piece? -----------° counterclockwise from the +x-axis
6. An astronaut in space becomes unteathered from her space craft while tightening bolts on a satellite, and she knows that the conservation of momentum is her only hope to safely get back to her ship. She turns her back to the ship and throws her 3.2-kg wrench in the direction pointing away from the ship. If the astronaut and her space suit have a combined mass of 120 kg and she is able to throw the wrench with a speed of 1.7 m/s, how fast will she move toward the space craft? Hint: you can assume that the astronaut is initially at rest relative to the space craft.

1. Refer to figure 1. Two carts collide and merge together. Calculate the final velocity of the merged carts, determine whether it was an elastic or inelastic collision, and whether energy was conserved or not. m₁ m₁ = 10.0 kg V₁ = 8.00 m/s Figure 1 m₂ m₂ = 30.0 kg V₂ = 0.00 m/s m3 = 40.0 kg V = ?
1.) A car (mass=400 kg) is traveling down a country road (speed is 10 m/s) when it collides with a deer (mass=200 kg) which is running in the opposite direction (speed is 2 m/s). The collision results in the deer getting stuck on the windshield. Treat this collision using the 'conservation of momentum' principle: a) Draw a sketch - label each MASS and each VELOCITY (with arrows for direction). b) Calculate the final speed of the car (remember the deer is stuck on top of the car) after collision (Note: they stick together to form a single mass)
A block with mass m and a velocity v10 collides with a block M at rest. At some time later after the collision the two masses have velocities v1 and v2.

The system consists of the two blocks. a) the mechanical energy of the system is conserved, but the momentum of the system is not b) the momentum of the system is conserved, but the mechanical energy of the system is not conserved c) neither the momentum nor the mechanical energy of the system need be conserved
