A 2.30 kg block slides down a frictionless incline from rest at the top (length = 2.40m, angle = 55°) and has a measured speed of 6.28 m/s at the bottom. The block is then slid down a rough incline of same length and angle and found to achieve a speed of 4.90 m/s. What is the best answer for the average frictional force experienced by the block while sliding down the second incline?
