To move a large crate across a rough floor, you push on it with a force...
To move a large crate across a rough floor, you push on it with a force F at an angle of 21 ∘ below the horizontal, as shown in the figure.(Figure 1) Part A Find the acceleration of the crate if the applied force is 380 N , the mass of the crate is 32 kgand the coefficient of kinetic friction is 0.30. Express your answer using two significant figures.

You push a crate of mass m up a ramp inclined at an angle A with a force parallel to the ramp but of varying magnitude. The coefficient of friction between the crate and ramp is u, and the speed of the crate, which starts from rest, is v at the end of the ramp of length d. a) Use the work-energy theorem to find the work done by the non-constant force in moving the crate up the ramp. b)...
