How much force does he use order to maintain constant speed

Reference no: EM13268335

1. A man pushes a wooden crate on wooden floor. The direction of the force is 30o downward relative to the horizontal (the man is taller than the height of the crate).

(a) How much force does he use in order to maintain a constant speed?

(b) How much work is done if he pushes the crate over a distance of 25.0 kg? Kinetic friction coefficient for wood/wood is 0.50.
