A boy pulls a sled at a constant speed 0.6 m/s by applying a force of 350 N. How much work will be done during 1800 s?

What we know:
Constant speed= .6m/s
Force= 350N
Time = 1800 sec
Work=force × distance

What we need to find:
How much work is done in 1800 seconds.

Distance= speed×time
=.6m/s × 1800s=1080 m

Work= 350N × 1080m
=378000 joules
