An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.25 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 39.0 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target?

A 83.2 g marble moving at 10.2 m/s approaches and collides head-on with a stationary 41.8 g marble. Assuming that the collision is elastic, what are the corresponding kinetic energy of each marble?

A 6.0 ✕ 104 kg space probe is traveling at a speed of 12000 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 3.0 ✕ 105 N over a distance of 2400 km. What is the final speed of the probe? m/s

A 22 g golf ball is placed at the top of a loop de loop track 45 cm above the top of a desk and released from rest. After the ball moves through the track, it rolls off of the table. If the table is 1.75 meters tall, how far does the golf ball travel before hitting the ground? (Friction and air resistance are negligable)

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.10 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 42.0 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target? m/s

A 8.3-kg falcon catches a 2.5-kg dove from behind in midair. What is their velocity in unit of m/s after impact if the falcon’s velocity is initially 42 m/s and the dove’s velocity is 1.8 m/s in the same direction?

Gayle runs at a speed of 3.65 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back and together they continue down the hill. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 48.0 kg, the sled has a mass of 5.45 kg and her brother has a mass of 30.0 kg. m/s

A 66-kg skier, initially at rest, slides down a hill 25 m high, then has a completely inelastic collision with a stationary 72-kg skier. Friction is negligible. What is the speed of each skier immediately after the collision?

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.45 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 37.5 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target? m/s

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.35 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 42.0 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target? m/s
