A block slides down a rough plane inclined at an angle of 15° to the horizontal. The coefficient of sliding friction between the block and the plane is u = 0.22. Calculate the magnitude of the acceleration of the block, in ms-2, to two significant figures. (Take the magnitude of the acceleration due to gravity, g, to be 9.8 ms-².) S The magnitude of the acceleration is ms -2 (to 2.s.f.).
