Problem: A freight company uses a compressed spring to shoot 1.90 kg packages up a 1.00-m -high frictionless ramp into a truck, as the figure shows. The spring constant is 371 N/m and the spring is compressed 33.0 cm .What is the speed of the package when it reaches the truck?A careless worker spills his soda on the ramp. This creates a 50.0-cm-long sticky spot with a coefficient of kinetic friction 0.300. Will the next package make it into the truck?
