Answer:
a = 0.41 [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
where:
F = force [N]
m = mass = 87 [kg]
a = acceleration [m/s²]
The frictional force will be taken as negative, since it opposes the movement of the block.
