 P: 403 Coefficient kinetic friction and kinetic friction You can calculate the acceleration a of the block by using the formula $$s=(1/2)at^2$$ where s=4.0m, t=2.0s. Then you should calculate all the forces acting on the x-axis (axis parallel to the incline) which are the kinetic friction T and component of weight on the x-axis $$B_x$$. It will be $$B_x-T=ma$$ where m the mass of block and a the acceleration you calculated on first step. From the last equation you ll be able to find the coefficient and the kinetic friction T.
