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)

A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this process, what is the work done on the cabinet by the friction force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

QUESTION 16 A crate of mass, m, slides down a plane inclined at an angle, 0, to the horizontal for a distance x down the incline. If the coefficient of kinetic friction between the inclined surface and the crate is µk. what is the work done by friction? a. -Hkmgxcose b. -mgxcose C. -mgxcose/µk d. -µkmgxtane e. -mgxsin0

A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this process, what is the work done on the cabinet by the normal force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
