An 87 kg wide receiver is running at 9.4 m/s and is hit by a 110 kg linebacker traveling in the opposite direction. After the collision, the two players move together in the receiver’s original direction at a speed of 1.6 m/s. How fast was the linebacker moving before the collision?

While a giant man stands on the top of a building, an elephant slams into him at a speed of 360 m/s. The giant man grabs onto the elephant during the impact and they are thrown from the top of the building. If the giant has a mass of 10 * 103 kg and the elephant has a mass of 3.9 * 103 kg, how fast are the two going as they go off the top of the building?

A car of mass 1000.0 kg moving at 20.0 m/s collides with a 5000.0 kg truck at the initial velocity of 10.0 m/s. After the collision, the car stops. Neglecting friction, what is the velocity of the truck after the collision? 20 m/s 10 m/s 8.0 m/s 12 m/s 10.0 m/s 14 m/s

A train car traveling east at 2 m/s collides with two stationary train cars parked next to each other so that they touch but are not coupled. In the collision, the incoming car engages the train coupler on the car that it hits. With what speeds are the cars moving after the collision? Cars 1&2 have the same mass of 10,000 kg, while car 3 has a mass of 20,000 kg.

A 50.0-kg boy runs at a speed of 10.0 m/s and jumps onto a cart as shown in the figure.  The cart is initially at rest.  If the speed of the cart with the boy on it is 2.50 m/s, what is the mass of the cart ?

Casey is driving a 1600 kg car toward the east. She goes through an intersection at a speed of 16 m/s (approximately 35 mph), the speed limit on both roads of the intersection. Kerry is driving a car of mass 1200 kg into the intersection, going north, and doesn’t see or doesn’t heed a red light, and slams into Casey’s car. The cars lock together and skid to a stop. Later, the two review the scene with the police. Skid marks from the instant after the collision reveal that the two cars were moving exactly northeast. Kerry claims to have been driving at the speed limit, but Casey says that Kerry seemed to be going over the speed limit before the collision. Who is correct? Use the concept of conservation of momentum to make your case.

At the intersection of Texas Avenue and University Drive, a yellow, subcompact car with mass 950 kg traveling east on University collides with a maroon pickup truck with mass 1700 kg that is traveling north on Texas and ran a red light (Figure 1). The two vehicles stick together as a result of the collision and, after the collision, the wreckage is sliding at 16.0 m/s in the direction 24.0° east of north.

Godzilla is fighting Mothra in Tokyo. Godzilla climbs a tall building and, while standing on the top of the building, Mothra slams into him at a speed of 400  m/s. Godzilla grabs onto Mothra during the impact and they are thrown from the top of the building. If Godzilla has a mass of 9 * 10 3 kg and Mothra has a mass of 3.1 * 10 3 kg, how fast are the two monsters going as they pitch from the top of the building?

On a frictionless air track, a blue glider with a mass 0.200kg is moving to the right with a speed if 8.00m/s. It strikes a red glider that has a mass 0.600kg and that is initially at rest. After the collision, the blue glider is moving to the left with a speed of 2.40m/s. a) what are the magnitude and direction of the velocity of the red glider after the collision?

Standing and facing each other, two hockey players push off and move in opposite directions. The second player, of mass m₂ = 58 kg, acquires a speed of v2 = 0.32 m/s. Find the speed of first player if m₁ = 25 kg. V1 = m/s
