I need to know if 6-9-1-3 (observed) are significantly different from expected (5-5-5-4) I do not think that they are, and I get a ChiSq of 6.85 and a p=0.077, with a df of 3, but I am not sure what that really means. Are my results correct, and if so, will you please explain.

The coefficient of kinetic friction is 0.60 (the slope angle is 60°).

What is the acceleration of the block if
(a) it is sliding down the slope, and
m/s2
(b) it has been given an upward shove and is still sliding up the slope?
m/s2

A 1400 N crate is being pushed across a level floor at a constant speed by a force F of 300 N at an angle of 20° below the horizontal a) What is the coefficient of kinetic friction between the crate and the floor?

(b) If the 300 N force is instead pulling the block at an angle of 20° above the horizontal as shown in Figure P4.31b, what will be the acceleration of the crate. Assume that the coefficient of friction is the same as found in (a).
m/s2
