A 70.0 kg archer, standing on frictionless ice, shoots a 200 g arrow at a speed of 100 m/s. What is the recoil speed of the archer? A 30 kg beaver is standing on the ice minding his own business. This same arrow travelling at 100 m/s bounces off the beaver, causing the beaverto slide across the ice at 1.2 m/s. What is the rebound velocity ofthe arrow? What percent of kineticenergy was conserved in the collision with the beaver?...

Question 1 20 pts For which of the following scenarios would the total momentum of the system not be conserved? Select all that apply. A bullet is shot at a downward angle (below the horizontal) into a block of wood at rest on a horizontal, frictionless surface. The system consists of the bullet and the block. Two balls moving in free fall motion such that they collide while one ball is moving downward and the other ball moving upward. The...

2. (30 pts) (based on Ohanian 11.41 homework problem) A woman of mass Mw and a man of mass MM face each other on a frictionless ice po standing still a distance L apart. The woman holds a ball of mass MB.

Three ice skaters meet at the center of a rink and each stand at rest facing the center, within arm’s reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass mA = 80.0 kg moves in the negative y-direction at 3.50 m/s and skater B with mass mB = 75.0 kg moves in the negative x-direction at 4.00 m/s. Find the x-...

Two hockey pucks (ma-1.20 kg and mg = 1.40 kg) slide on a flat sheet of frictionless ice and then collide with each other. The diagram below shows a top-down view of the ice. Initially, hockey puck A moves in the *x direction with speed 4.80 m/s, while hockey puck B moves in the +x direction with speed 2.30 m/s. After the collision, hockey puck A moves off at an angle of 23.5' above the +x axis and hockey puck...
