Question

How much weight is lifted if 1000 joules of work are done in lifting it to a height of 0.85 meters

Answer 1

W = Fd

 

where:

W = work

F = force

d = distance

 

 

Because their is lifting, force acts as a weight.  So when we solve for the force, we get our weight.

 

F = W / d

 

F = (1000  Nm) / (0.85 m)

 

F = 1176.471 N
