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 figureA figure shows a package being loaded into a 1.0-meter-tall truck along a ramp by a push from a spring. There is a 50-centimeter-long “sticky spot” in front of the ramp. 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?
