Two laborers are controlling the slide of a 400 kg crate down a ramp at constant velocity. One of them is pulling a rope (T) and the other is holding (resisting) by hand (P). The angle of contact each makes with the crate is 30.0 degree. Draw a free-body diagram for the crate and identify all forces. (2 pts.) If the coefficient of kinetic friction between the crate and the ramp is 0.20, the ramp angle is 25.0 degree, and...

What is the MAXIMUM weight ww that can be used to hold
this crate stationary on the ramp? Include free-body diagrams of
the two masses.
Now assume that the weight w=3000N. What is the acceleration of
the crate?
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 kinetmatics and the acceleration derived
in the previous subquestion, and using energy considerations.
