1. 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. The mass of the crate
is 32.0 kg. The coefficients of static and kinetic friction are 0.62 and
0.42 respectively.
(a) What force F is required to start the crate moving?
(b) If the force F is 365 N, the crate will move horizontally across the room. What is the acceleration?
