A woman pushes a crate along the floor of a warehouse with a force of 31.9 N directed downward at an angle of 23.6° from the horizontal. If the crate has a mass of 11.9 kg and the coefficient of friction is 0.0975, find...

(a) the force of friction
b. (b) theacceleration

(a) (0.0975)*(M*g + 31.9 sin23.6) = 12.62 N

(b) [31.9 cos23.6 - 12.62]/M = 1.40 m/s^2
