Question

A 115.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 46.0 deg with the horizontal.what is the magnitude of the normal force between the ramp and the box?

The applied force= 1167.04N

Answer 1

m*g = 115 * 9.8 = 1127 N. = Wt. of box.

Fn = 1127*cos46 = 782.9 N. = Normal
force.
