Estimate the magnitude of the acceleration of the box

Reference no: EM13556998

A box mass 5.00 kg moves on a ramp that is inclined at 6.9° above the horizontal. A person is applying a constant force F=70.0 N to the box, The direction of F is parallel to the ramp and directed up the ramp. The coefficient of kinetic friction between the box and the ramp is,uk =0.300.

a) What is the magnitude of the friction force that the ramp exerts on the box?

b) What is the magnitude of the acceleration of the box?
