Answer:
a = - 0.209 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
We will take the positive forces to the right and the negative forces to the left.
[tex]155-277+113=43*a\\-9=43*a\\a = - 0.209[m/s^{2} ][/tex]
The negative sign means that the box accelerates in a negative direction to the left.
