Question

You are pushing a 3.95-kg box toward the right as it moves, in the direction of your push, over a patch of rough grass. Construct the free-body diagram for the box by correctly arranging the arrows in the diagram to the right. Each force acting on the box should be indicated by an arrow starting at the dot in the center of the box. Any arrow you don't use should remain entirely in the gray area at top 9 The arrows are labeled according to the following key W = weight of box Fforce of your push g- acceleration due to gravity N = normal force from groun f= friction force from grass If the magnitude of your push is 25.8 N, and the coefficient of kinetic friction with the grass is 0.350, what will be the magnitude and direction of the acceleration of up to the right down to the left Number m/ s Select answer

Explanation / Answer

Net horizontal force Fnet = F - µmg = 25.4N - 0.350x3.95x9.81

Fnet = 25.4-13.55 =11.85N

Then a = Fnet / m = 11.85/3.95 = 3.0m/s²
