A worker uses a cart to move a load of bricks weighing 680 N a distance of 10 m across a parking lot.
2 answers:
The answer is B because force = work times distance so you would multiply 209N times 10m
When you are finding work, the easiest way is to use the formula.
W = F*D
Where F is the force and D is the distance. Simply take the constant force of 209N and multiply it by the distance of 10m. Which will give you 2090J

Newton's 2nd law of motion:
Force = (mass) x (acceleration)
Divide each side by (mass):
Acceleration = (force) / (mass)
= (100 N) / (50 kg)
= 2 m/s²
