Problem: A box of books weighing 304 N is shoved across the floor of an apartment by a force of 543 N exerted downward at an angle of 39.5 degrees below the horizontal. The acceleration of gravity is 9.8 N. If the coefficient of kinetic friction between box and floor is 0.473,
Part A: How long does it take to move the box 6.45 m, starting from rest?
Please show your work, so I can understand process. Thanks!
