Erin uses 30N of force to push a lawn mower 10 meters. How much work does she do?
A. 30 J
B. 3’000 J
C. 300 J
D. 3 J
The formula to calculate work is given by W = F * d, where W is work, F is force, and d is distance.
Given that Erin uses 30N of force and pushes the lawn mower for 10 meters, the work done can be calculated as:
W = 30N * 10m = 300 J
Therefore, Erin does 300 J of work.
The correct answer is C. 300 J.
