A 2000-N crate is to be held in place on a ramp that rises at 30.0°
above the horizontal (see figure). The massless rope attached to
the crate makes a 22.0° angle above the surface of the ramp. The
coefficients of friction between the crate and the surface of the
ramp are μk=0.450 and μs=0.650. The pulley has no appreciable
mass or friction.
A. What is the MAXIMUM weight w that can be used to hold
this crate stationary on the ramp? Include free-body diagrams of
the two masses.
B. Now assume that the weight w=3000N. What is the acceleration of
the crate?
C. Find the speed of the masses after the weight w=3000N has
dropped a distance of 1.6m after being released from rest. Find
this speed two ways: using kinematics and the acceleration derived
in the previous subquestion, and using energy considerations.
