A box of books weighing 323 N is shoved across the floor by a force of 477 N exerted downward at an angle of 35° below the horizontal.
(a) If μk between the box and the floor is 0.51, how long does it take to move the box 4.80 m starting from rest?
(b) What is the maximum coefficient of kinetic friction between the box and the floor that allows the box to move from this applied force.
Physics help! -
Anyone know how to do this
