Problem
A block of mass 5kg rests on a horizontal rough surface for which the coefficient of kinetic friction is 0.20. A force of 30N is applied to the block at an angle of 37∘ above the horizontal.
(i) Resolve the applied force into horizontal and vertical components.
(ii) Calculate the normal reaction exerted by the surface on the block.
(iii) Determine the magnitude of the kinetic frictional force acting on the block.
(iv) Find the acceleration of the block along the surface.
