Wb = M*g = 10 * 9.8 = 98 N.
Fn = 98-40*sin30 = Normal force.
Fk = u*Fn = Force of kinetic friction.
a = (Fap*Cos30-Fk)/M.
A 10-kg box is pulled along a horizontal surface by a
force of 40N applied at a 30° angle above
horizontal. The coefficient of kinetic friction is 0.3.
Calculate the acceleration.
