Question

Physics

A.) We start with some review problems A crate of mass 49.6 kgrests on a level surface, with a coefficient of kinetic friction0.161. You push on the crate with an applied force of 345 N. Whatis the magnitude of the crate s acceleration as it slides?

B.) You place a crate of mass 37.4 kg on a frictionless2.91-meter-long incline. You release the crate from rest, and itbegins to slide down, eventually reaching the bottom 1.26 s afteryou released it. What is the angle of the incline?

C.) This time we have a crate of mass 38.7 kg on an inclinedsurface, with a coefficient of kinetic friction 0.249. Instead ofpushing on the crate, you let it slide down due to gravity. Whatmust the angle of the incline be, in order for the crate to slidewith an acceleration of 7.86 m/s^2?
