A 250-kg crate is on a rough ramp, inclined at 30 above the horizontal. The coefficient of kinetic friction between the crate and ramp is 0.22. A horizontal force of 5000 N is applied to the crate, pushing it up the ramp.

What is the acceleration of the crate?
A) 8.4 m/s2
B) 10 m/s2
C) 12 m/s2
D) 13 m/s2
E) 3.4 m/s2

Question 2

A box is sliding down an incline tilted at a 12.0 angle above horizontal. The box is initially sliding down the incline at a speed of 1.50 m/s. The coefficient of kinetic friction between the box and the incline is 0.340.

How far does the box slide down the incline before coming to rest?
A) 0.920 m
B) 2.33 m
C) 1.78 m
D) 0.720 m
E) The box does not stop. It accelerates down the plane.
