A 1520-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 k = 0.450 and s = 0.650. The pulley has no appreciable mass or friction. What is the MAXIMUM weight w that can be used to hold this crate stationary on the ramp?
 
  What will be an ideal response?

Question 2

Two weights are connected by a massless wire and pulled upward with a constant speed of 1.50 m/s by a vertical pull P. The tension in the wire is T (see figure). P is closest to
 
  A) 25 N.
  B) 125 N.
  C) 187.5 N.
  D) 245 N.
  E) 1225 N.
