A company claims its ramp and crate system has a super precise coefficient of friction. The crate has a mass of 3.44 kg and starts from rest at the top of a 32.50 inclined ramp and slides 2.00 m down the incline in 1.75 s. Follow the steps of the problem to find the coefficient of friction, and also figure out how fast the crate was going at the bottom of the ramp. (a) What is the magnitude of the acceleration of the crate (in m/s2)? m/s2 (b) What is the frictional force (in N) acting on the crate? (Enter the magnitude.) N (c) What is the coefficient of kinetic friction between the crate and the incline? (d) What is the speed of the crate (in m/s) after it has slid 2.00 m? m/s
