Question

A force of 450 newtons was necessary to lift a cement block. a total of 250 joules of work was done. how far was the cement block lifted?

Answer 1

0.56 meters

Step-by-step explanation:

Work = Force x Displacement

Let X be the displacement.

250 Joules = (450 Newtons)*X

X = (250 Joules)/(450 Newtons)

A Joule is 1kg*m^2/sec^2 or Newton*m

A Newton is 1kg*m/sec^2

X = (250 Newton*m)/(450 Newtons)

X = 0.56 meters
