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

Your mass is 73.3 kg, and the sled s mass is 10.1 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 5.48 m/s. What will be your speed on the ice after jumping off?     0.38 m/s     1.22 m/s     0.99 m/s     0.76 m/s

You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 64.8 kg, and the sleds mass is 21.5 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 4.25 m/s. What will be your speed on the ice after jumping off?     0.71 m/s     2.12 m/s     1.77 m/s     1.41 m/s

5. The figure shows three balls of clay moving on a frictionless horizontal surface just before a collision. The three collide simultaneously and stick together. Find the speed and direction of the blob of clay after the collision. Draw the blob after the collision and show its velocity vector. 40 g 45° 4.0 m/s 3.0 m/s 30 g 2.0 m/s 20 g

A pistol fires a 2.57 g bullet.  The bullet then strikes a 3.07 kg wooden block resting on a horizontal frictionless surface.  The block and the embedded bullet then slide across the surface as one object at a velocity of 1.22.  Find the speed of bullet before the bullet is embedded in the block.

A 320-g air track cart traveling at 1.25m/s suddenly collides elastically with a stationary 270-g cart. What is the speed of the 320-g cart just after the collison?  The answer should be 0.11m/s

A 25 gram bullet is fired at 124 m/s into a 5.00 Kg block, the bullet penetrates the block and exits at 99 m/s. what is the speed of the block after the bullet goes thru it?

A red 150 g toy car slides down a 40 degree frictionless ramp. At the bottom, just at it exists onto a horizontal part of the slide, it collides with a purple 400 g car at rest. How high should you make the water slide so that the red toy car gives the purple car a speed of 300 cm/s?

A 10,000 kg railroad car is moving at 2.00 m/sec when a 4000 kg load of gravel is suddenly dropped in. What is the car’s speed just after the gravel is loaded?

A knife thrower throws a knife toward a 300 g target that is sliding in her direction at a speed of 2.30 m/s on a horizontal frictionless surface. She throws a 22.5 g knife at the target with a speed of 38.0 m/s. The target is stopped by the impact and the knife passes through the target. Determine the speed of the knife (in m/s) after passing through the target.
