A 900-N crate is being pushed across a level floor at a constantspeed by a force of 250 N at an angle of 20.0° below thehorizontal, as shown in the figure below.
(a) What is the coefficient of kinetic friction between the crateand the floor?
_______________________
(b) If the 250 N force is instead pulling the block at an angle of20.0° above the horizontal as shown in the figure, what will be theacceleration of the crate? Assume that the coefficient of frictionis the same as that found in part (a).____________ m/s2
