A block on a ramp has a mass M=12.6 kg, F=171 N, θ= 23.0o. The crate has an initial speed of 1.75 m/s. It is pulled a distance of 8.50 m. Assume that the coefficient of kinetic friction between the ramp and the block is 0.2.
What is the magnitude of the net force acting on the block?
What is in degrees (as a positive number measured in the counterclockwise direction, relative to the positive horizontal x-direction) the direction of the normal force on the block?
