Draw a free body diagram and Apply Newton's 2nd law in both direction.
60 kg chair is pulled along a rough horizontal surface under the action of a 200N force 30 degrees up from horizontal, as shown the acceleration of the chair is 1.5 m/s^2.
a) Determine the normal force on the chair.
b) Determine the frictional force acting on the chair.
c) Determine the coefficient of friction between the chair and the surface.
