A freight company uses a compressed spring to shoot 2.0 kg packages up a 1.0 m high frictionless ramp into a truck, as the figure shows. The spring constant is 500 N/m and the spring is compressed 30 cm. a. What is the speed of the package when it reaches the truck? b. A careless worker spills his soda on the ramp. This creates a 50 cm long sticky spot with a coefficient of kinetic friction 0.30. Will the next package make it into the truck?
