A box of mass m is dropped from a height H above a spring. The platform has negligible mass. The spring has spring constant k. (a) By what amount is the spring compressed? Your answer requires the quadratic equation; to choose the correct root, note that x needs to be positive. (b) What is the speed of the box when it is first in contact with the platform? (c) What is the maximum speed of the box? Hint: the box...

A box with mass m = 1.2kg on an inclined frictionless surface is released from rest from a height h = 1.75 m. After reaching the bottom of the incline the box slides with friction (uk = 0.25) along a horizontal surface until coming to a rest after a distance d. 1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names. 2. Draw a free body diagram for...
