Question

In the end of the Chapter 4 Problem 4.4 of your book consider that the trunk has mass M travels at a constant velocity along a frictionless inclined and the angles involved are θi and θs, where θs corresponds to the angle with respect to the direction of motion and θi is the angle of the inclined. What are the simplified expressions for the tension on the rope and the normal force on the trunk in terms of M, g and the angles?

 

4.4 . A man Is
75.0°
loading ramp of a mover's truck. The
ramp has a slope angle of 20.0°, and
the man pulls upward with a force F
whose direction makes an angle of 30.0°
with the ramp (Fig. E4.4). (a) How large a force F is necessary for the
component F parallel to the ramp to be 90.0 N? (b) How large will the
component F, perpendicular to the ramp be then?
