A block of mass m slides down from rest on a rough incline of length 8m where the incline makes an angle of 30° with the horizontal. The block comes to rest on the rough horizontal surface after sliding for 4 m. The coefficient of kinetic friction on the incline is 0.30. The coefficient of kinetic friction on the horizontal surface is different from the incline, find this value using two approaches: (i) Using Newton's laws of motion and Kinematics and 30⁰ (ii) Using Work-Kinetic Energy Theorem (Give answer to 2 sig. figs.) 4 m 8 m WA
