A 38.5g block is sliding at 5.0m/s on the upper surface which is frictionless and 1.00m above the lower frictionless surface. The block slides down a ramp that is at an angle of 18.5 degrees. What must the friction force on the ramp be in order for the block to have a velocity of 5.5m/s at the bottom of the ramp?? I got the equation and an answer, but I am not sure if its right. how can i finish?
