Hi there!
We can use Newton's Second Law to solve:
∑F = Net force (N)
m = mass (kg)
a = acceleration (m/s²)
Rearrange the equation to solve for acceleration:
Plug in the values given to solve for the magnitude of the force.
**However, if we want to assign the left direction to be NEGATIVE, then the acceleration of the cart due to a leftward net force would be -5.96 m/s².
