Question
A freight company uses a compressed spring to shoot 1.80 kg packages up a 1.00-m -high frictionless ramp into a truck, as the figure(Figure 1) shows. The spring constant is 321 N/m and the spring is compressed 35.0 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 0.55. How high up the ramp will the package go after crossing the sticky spot?
