A 483 kg car parked on a parking lot is struck from the rear by a 900-kg truck. The two vehicles become entangled, moving along the same path as that of the truck. If the entangled car and the truck move with the velocity of 10.0 m/s after the collision, what was the velocity of the truck before the collision?

A 60-kg swimmer suddenly dives horizontally to the left from a 100-kg raft with a speed of 2.5 m/s. The raft is initially at rest. What is the velocity of the raft immediately after the diver jumps?

Ball A, whose mass is 12.0 kg, is moving with a velocity of 37.0 m when it suddenly hits another ball at rest, Ball B. After the collision, Ball A continues to move with a velocity of 19.0 m/s while Ball B moves with a velocity of 4.00 m/s. What is the mass of Ball B?

A 1500 kg car moving to the right with a speed of 20 m/s collides with a bigger car of mass 2000 kg which is at rest. If the two cars lock together, what is their common velocity after the collision?

A car of mass 1388 kg traveling at 18.67 m/s Collided and sticks to another car with a mass of 1488 kg. what is the resulting velocity of the two cars right after the collision assuming that there is no friction present?

Two 2712 kg train cars roll toward each other (Car A at 0.34 m/s, Car B at -2.5 m/s) on a level track. After they collide and couple together, what is the final velocity of the two-car object?

A 5.65.6 kg block is travelling rightwards with speed 12.812.8 m/s. It collides with 3.23.2 kg which is travelling 22 m/s leftwards. After the collision, the 3.23.2 kg block travels 8.58.5 m/s rightwards. What is the velocity of the 5.65.6 kg block? Treat the leftward direction as the negative direction. Is this collision elastic or inelastic?

A girl of mass 47.0 kg jumps off the bow of a 66.0-kg canoe that is initially at rest. If her velocity is 1.90 m/s to the right, what is the speed of the canoe after she jumps?

Carry Collision Insurance! A 1,906 kg car stopped at a traffic light is struck from the rear by a 953-kg car. The two cars become entangled, moving along the same path as that of the originally moving car. If the smaller car were moving at 26.7 m/s before the collision, what is the velocity of the entangled cars after the collision? (Assume the smaller car initially moves in the positive direction.) SOLUTION Conceptualize This kind of collision is easily visualized, and one can predict that after the collision both cars will be moving in the same direction as that of the initially moving car. Because the initially moving car has only half the mass of the stationary car, we expect the final velocity of the cars to be relatively ---Select--- Categorize We identify the two cars as an isolated system in terms of momentum in the horizontal direction and apply the impulse approximation during the short time interval of the collision. The phrase "become entangled" tells us to categorize the…

Two cars approach an ice-covered intersection. One car, of mass 1.10  103 kg, is initially traveling north at 10.1 m/s. The other car, of mass 1.55  103 kg, is initially traveling east at 10.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Magnitude:
