A 14 kilogram box is sliding up a ramp that is elevated at an angle of 15 degree above the horizontal. The coefficient of Kinetic friction between the box and the ramp is 0.26; the coefficient of static friction is 0.35. The initial speed of the box at the bottom of the ramp is 3.2 m/s.
A) Evaluate the acceleration of the box.
B) Evaluate the distance that the box slides along the ramp before coming to a rest.
C) The top of the ramp is .8 meter farther along the ramp than the distance estimated in part B. Find an additional constant force that must be exerted on the box, parallel to the ramp so that it will come to rest at the top of the ramp?
