Question

Two electric motors drive two elevators of equal mass in a three-story building 10 meters tall. Each elevator has a mass of 1,000kg. Calculate the work done by each motor. Express answer in scientific notation.

Answer 1

\[work=force \times distance\]\[distance=10m\]\[force =1000kg \times 10ms ^{-1}=10000N\]\[work=10000N \times 10=100000J\]\[100000J=1.0 \times 10^{5}J\]Does that make any sense? I wasn't really sure how to explain it. If you need more explanation, please tell me and I'll try again :)

Answer 2

I got it thank you :)
