2. A box is placed on a horizontal surface and pushed to the left by a force of 600 N applied at an angle of 20 degrees below the horizontal. If the mass of the box is 50 kg, and the coefficient of kinetic friction between the box and the surface is 0.3, calculate the following: a.) The frictional force acting on the box.

b.) The work done by friction on the box.

c.) The work done by the applied force on the box.

d.) The work done by the normal force from the table on the box.

e.) The work done by gravity on the box.

f.) The speed of the box after it has travelled 25 meters to the left.

g.) The total power developed in the box during the 25 meter slide.

power is the rate of doing work. Power is work divided by the time it takes to do the work. Power is also net force multiplied by the average velocity
