1. Bruce stands on a bank beside a pond, grasps the end of a 10.0 m long rope attached to a nearby tree and swings out to drop into the water. If the rope starts at an angle of 38.0° with the vertical, what is Bruce's speed at the bottom of the swing?
_____m/s
2. Josie and Charlotte push a 20 kg bag of playground sand for a sandbox on a frictionless, horizontal, wet polyvinyl surface with a constant, horizontal force for a distance of 8 m, starting from rest. If the final speed of the sand bag is 0.14 m/s, what is the magnitude of the force with which they pushed?
