A book is being pushed by a force of (10-2t2) N that is angled downward from the horizontal by 23 deg. for 0.8 s. How far did the book move in this time if it started from rest? Assume that the book is sliding on a flat, horizontal surface with a coefficient of kinetic friction of 0.1.assume mass of book is 0.5kg.

A 6.4 kg crate is pushed with a constant horizontal force of 22 N on a flat surface with kinetic friction coefficient µk = 0.25. If it starts from rest, what is its speed after 12 meters? (Use the work-energy theorem; remember that the formula uses the total net work of all forces present).
A particular box, weighing 172 N, is being pushed on a horizontal floor. It requires a 43-Newton horizontal push to "break" the static friction, and 23 Newtons to keep it sliding with a constant velocity. (a) What is the coefficient of static friction? Correct: Your answer is correct. (b) What is the coefficient of kinetic friction?0.13 Incorrect: Your answer is incorrect. (c) If more stuff is put into the box, bringing its total weight up to 210 N, the maximum...

The refrigerator is 2m high and 1m wide. What is the max height above the inclined plane that...
A force of 85.5 N in the horizontal direction is required to set a 25.4-kg box, initially at rest on a flat surface, in motion. After the box begins to move, a horizontal force of 55.5 N is required to maintain a constant speed. (a) What is the coefficient of static friction between the box and the surface? (b) What is the coefficient of kinetic friction between the box and the surface?
Starting from rest, a 3.2-kg box is pushed on a horizontal floor with a force of 482.6 N parallel to the floor. The coefficient of kinetic friction between the box and the floor is 0.5. What is the kinetic energy of the box after it has been pushed with the constant force of 5.8 meters?
