-2 points CJ10 4P 119 The drawing shows a 24.6-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, Fs and F', are applied to the crate, and t begins to move. The coefficient of kinetic friction between the crate magnitude direction and the floor is px-0.386. Determine the magnitude and direction (relative to the x axis) of the aceleration of the crate. m/s2 Additional Materials Section 4.1 Save Progress Submit Home My Assignments Extension Reques

Explanation / Answer

Fx = 54.0 + 88.0cos55

Fx = 104.4747 N

Fy = 0 + 88.0sin55

Fy = 72.085 N

F = (72.085^2 + 104.4747^2)
F = 126.93 N

tan = 72.085 / 104.4747

= 34.6° CCW from the positive x axis

Fnet = ma

F - mg = ma

a = (F - mg) / m

a = (126.93 - 0.386*24.6*9.81) / 24.6

a = 1.3730 m/s^2
