A box of mass 40 kg is initially at rest on a flat floor. The coefficient of kinetic friction between the box and the floor is µk = 0.40. A woman pushes against the box with a force of 250 N that makes an angle of 30° with the horizontal until the box attains a speed of 1.0 m/s. (a) What is the change of kinetic energy of the box? (b) What is the work done by the friction force...
