A total of 650 joules of work is done on a 50.-kilogram object as it is moved 8.0 meters across a level floor by the application of a horizontal force. Determine the magnitude of the horizontal force applied to the object
Given

W = 650 J
m = 50 kg
d = 8.0 m
bobpursley
work= force*distance

force=work/distance= 650J/8m= you do it, answer is in newtons.
Ok, thanks got it i was a little confused on that. It's 80 J
isn't it 80 N?
