3. A box having a mass equal to 10.0 kg is initially at rest on a horizontal, frictionless floor. A pulling force having a magnitude of 5.00 N is applied at an angle of 30.0° above the horizontal. The box is pulled a distance of 15.0 m. 7 ] = 5.00 N 30.0° (a) What is the work done by the pulling force? (b) What is the work done by gravity? (c) What is the work done by the normal force? (d) What is the total work done on the box? (e) What is the speed of the box after being pulled 15.0 m?
