Question
WE-2 A 65.0kg crate is initially moving at 5.00m/s up
a rough ramp. A horizontal force P=400N pushes
the crate 8.25m up the ramp, which is inclined 15°
with the horizontal. When sliding, the friction
force on the crate is 125N.
8.25m
a) Draw the free body diagram for the crate.
b) Apply the definition of work: Wk=FAs to
find the work done on the crate by each
force.
15.0°
c) Find the net work done on the crate.
d) Is the crate speed decreasing, constant, or
increasing? Explain how you know.
e) Find the speed of the crate after it has traveled the 8.25m using energy ideas (do not use Fnet=ma)
