A freight company uses a compressed spring to shoot 1.70 kg packages up a 1 m high frictionless ramp into a truck. The spring constant is 241 N/m and the spring is compressed 33.0cm.
1. What is the speed of the package when it reaches the truck?
2. A careless worker spills his soda on the ramp. This creates a 50 cm long sticky spot a coefficient of kinetic friction 0.300. Will the next package make it into the truck?
