a monkey pulls a box of bananas with mass 6.2 kg on a surface with a constant speed of 0.50 m/s. the applies force is at an angle of 20 degrees up with respect to the level floor. the coefficient of kinetic friction between the box and the surface is 0.20.
A) what should be the magnitude of the force the monkey applied to maintain the motion with constant speed?
B) how much is the normal force on the box?
