Question
A 65.0 kg box is pushed up a ramp inclined at 27.0°, as shown in Figure A1.15. The applied force (F) is horizontal and causes the block to move at
a constant speed. Determine the magnitude of the applied force, a. when the ramp is frictionless. b. when the coefficient of kinetic friction is 0.200.
