A 2.0 ð‘˜ð‘" package is released on a frictionless ramp inclined 53.1 ° above the horizontal, 4.00 ð‘š from a long spring with force constant 120 ð‘/ð‘š that is attached to the bottom of the incline. The mass of the spring is negligible.

What is the speed of the package just as it reaches the spring?

What is the maximum compression of the spring?

Suppose instead that the ramp were not frictionless and the coefficient of kinetic friction between the ramp and the package is ðœ‡ô°" = 0.20. What is the maximum compression of the spring in this case?
