A clerk moves a box of cans down an aisle by pulling on a strap attached to the box. The clerk pulls with a force of 185.0 N at an angle of 25.0 degrees with the horizontal. The box has a mass of 35.0 kg, and the coefficient of kinetic friction between the box and the floor is 0.450. Find the acceleration of the box.
horizontal force exerted on the box = 185 cos(25) = 167.7 N coefficient of friction k = 0.450 friction force = kmg = 0.450 x 35 x 9.8 = 154.3 N total horizontal force on the box = 167.7 - 154.3 = 13.4 N acceleration = F/m = 13.4 / 35 = 0.383 m/s^2
