A 60 kg archer, standing on frictionless ice, shoots a 120 g arrow at a speed of 95 m/s. a) Does the bow exert a constant force or a variable force on the arrow? b) Is this situation considered an isolated system or a non-isolated system? What other forces would you include in a free-body diagram? Would these other forces contribute to the velocity of either the arrow or the archer? c) What pair of forces exist that causes the arrow to fly and the archer to slide backward on the ice? Are these forces internal or external?

A 0.5 kg ball is dropped from a window. An archer shoots a 0.05 kg arrow to intercept the ball. When the ball is impaled it is traveling at -2 m/s in the y direction, and the arrow is traveling at 35 m/s at an angle of 20 degrees. What is the velocity of the pair after the collision in vector notation, magnitude, and direction? What is the impulse of the arrow?

A 750-g disk sliding along frictionless ice with a speed of 8.5 m/s strikes a stationary rod-disk combo 12-cm from its center-of-mass. This rod-disk combo is made from a 360-g rod that is 35-cm long, with 2 150-g solid disks of radius 7.0-cm attached, one on each end of the rod. After the perfectly elastic collision, the disk moves off along a path that is 28º above its original path, while the rod-disk combo spins about its center-of-mass as it...

A mass of 0.5 kg sits on a horizontal frictionless patch of ice. It is connected to a spring with a with a spring constant of k=5 N/m. The spring is initially relaxed. It is then pulled to the right and stretched by 0.1 meters. It is released afterwards to return to its equilibrium position at x=0 meters. "x" is the amount of displacement. Please use conservation of energy to find the velocity of the mass at 0.08 meters.
