Solve the following question:
Question: A block of mass 1.2 kg slides along a frictionless horizontal surface with an initial speed of 5.2 m/s. The block then encounters a rough patch that is 0.75 m long (after which the surface becomes smooth again). After sliding across the rough surface, the block's velocity has been reduced to 4.3 m/s.
Part A: Use the work-energy theorem to determine the coefficient of kinetic friction between the block and the rough surface.
I need help to find the coefficient of kinetic friction between the block and the rough surface.
