9). A 7.45 kg box is pulled along a horizontal surface by a rope that makes a 27.4angle with the horizontal. If the force of friction is 21.8 N, and the force applied through the rope is 49.7 N, what is the acceleration of the box?

10). A 10.5 kg box is pulled up an incline at 23.6to the horizontal. If the force of friction is 24.3 N and the acceleration of the box is 3.94 m/s²:

a) what is the force applied to the box?

b) what is the coefficient of friction between the box and the incline?
