A soldier pushes a crate of boxes (mass 12.0kg) with a force=155N parallel to the tarmac. The boxes move up the ramp of a C-141 that is inclined at 35 degrees. The coefficient of friction between the ramp and the box is 0.150

A) Calculate the work due to the gravitational attraction force on the boxes in pushing the box 4.50 up the incline.

B) Calculate the work due to friction in pushing the box4.50m up the incline.

C) The boxis initially at rest before it's pushed up the incline. Calculate the speed of the boxwhen it reaches 4.5 up the incline.
