A 2.80-kg block starts from rest at the top of a 30.0° incline and slides a distance of 1.70 m down the incline in 1.20 s. Find the magnitude of the acceleration of the block. Find the coefficient of kinetic friction between block and plane. Find the friction force (magnitude and direction) acting on the block. Find the speed of the block after it has slid 1.70 m (m/s).

You are pushing a wooden crate against a rubber floor. The two surfaces have a static coefficient of friction of 0.45 and a kinetic coefficient of friction of 0.38. The floor is horizontal, and the crate has a mass of 25.0 kg, and is initially at rest. You are pushing with a horizontal force of 155 N. What is the magnitude of the force of friction in this case? Give your answer in units of N, to three significant figures.
