A 0.015 kg marble moving to the right at 0.225 m / s makes an elastic head-on collision with a 0.030 kg marble moving to the left at 0.180 m / s. After the collision, the smaller marble is moving to the left at 0.315 m / s. Suppose that neither of the marbles rotates before or after the collision and that both marbles are moving on a frictionless surface. What is the velocity of the 0.030-kg marble after the collision?

A cart of mass 0.3kg traveling at 3m/s on a horizontal frictionless track collides with a cart of mass 0.45kg traveling at 2.5m/s towards it.  The carts stick together after the collision.  What is the final velocity of the carts

Two pieces of space debris drift toward each other, collide, and stick together. The first piece has a mass of 45 kg and a velocity of m/s just before the collision. The second piece has a mass of 65 kg and a velocity of m/s just before the collision. What is the velocity of their center of mass after the collision? O ( 0.73, 0.73, 4.95 ) m/s O ( 3.27, 3.27, 4.05 ) m/s O ( 9.00, -5.00, 9.00 ) m/s O ( -0.99, -0.99, 11.50 ) m/s O None of the above

A 0.84 kg ball moving horizontally at 9.0 m/s strikes a vertical wall and rebounds with speed of 5.0 m/s. What is the magnitude of the change in its linear momentum.

Object 1 with a mass of 4.70 kg, moving right at a speed of 7.80 m/s along a frictionless surface, collides head-on with Object 2 with a mass of 3.30 kg moving left at a speed of 10.6 m/s. After the collision, the Object 1 is moving left at 2.40 m/s.

A stationary firecracker explodes into two pieces. The piece shot to the right has a mass of 0.07 kg and is traveling 45 m/s. How fast is the smaller 0.04 kg piece, which travels to the left? Ignore friction and air resistance.

Consider a golf club hitting a golf ball. To a good approximation, we can model this as a collision between the rapidly moving head of the golf club and the stationary golf ball, ignoring the shaft of the club and the golfer.A golf ball has a mass of 46 g. Suppose a 200 g club head is moving at a speed of 40 m/s just before striking the golf ball. After the collision, the golf ball’s speed is 60 m/s. What is the momentum of the club + ball system right before the collision?A. 1.8 kg • m/s            B. 8.0 kg • m/sC. 3220 kg • m/s         D. 8000 kg • m/s

A 95 g projectile is launched at a speed of 22 m/s. It strikes a 1.7 kg stationary ball of clay, and becomes embedded in the clay. How fast does the combined projectile-clay unit travel immediately after the collision?

Please help. This is all one question!

an archer shoots an arrow toward a 0.3 Kg target that is sliding in her direction at a speed of 2.50 m/s on a smooth, slippery surface. The 0.0225 Kg arrow is shot with a speed of 35.0 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?
