A) A 50.0 kg box rests on a horizontal surface. The coefficients of static and kinetic friction between the box and the surface are 0.300 and 0.200, respectively. What is the friction force on the box if a horizontal 175 N push is applied to it? Explain.
B) A horizontal force of 250 N is applied to the box. After the box moves a distance d from rest, the speed of the box is measured to be 6.4 m/s. use the work-kinetic energy theorem to find the distance d the box has moved.
