A 237-kg crate is being pushed across a horizontal floor by a force P that makes an angle of 47.1 ° below the horizontal. The coefficient of kinetic friction is 0.217. What should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?

A 1000N crate is being pushed across a level floor at a constant seed by Force F which equals 300N at an angle 20 degrees below the horizontal. What is the coefficient of kinetic friction between the crate and floor? Also, if it is pulling the block at an angle 20 degrees above the horizontal, what is the acceleration of the crate?

A 1.00 × 10³-N crate is being pushed across a level floor at a constant speed by a force F of 3.00 × 10² N at an angle of 20.0° below the horizontal, as shown in Figure P4.23a. (a) What is the coefficient of kinetic friction between the crate and the floor? (b) If the 3.00 × 10²-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in Figure P4.23b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a)
