Question

A box of books wighing 339 N is shoved across the floor by a force of 506 N exerted downward at an angle of 33° below the horzontal. The acceleration of gravity is 9.81m/s^2. If µk between the box and the floor is 0.59, how long does it take to move the box 5.27 m, starting from rest? Answer in units of s.

Answer 1

break the pushing force into horiztonal and vertical components. The vertical force adds to weight to determine force normal,and friction. You have the horizontal force, the opposingfriction, determine acceleration. Thence distance is known, find time.

Answer 2

sry but im a blonde so not even half of that just made sense! :(

Answer 3

wat is the horizontal force??
