Finding Joules?

Question

Noo clue how to do this!!

Calculate how much work you need to move the 130 N trunk to a ledge 2 m above.

130 J

260 J

26 J

Answer 1

a joule is a Nm or newton meter. work is force times displacement. so 130Nx2m= 260Nm= 260J

Answer 2

Work is the product of force and distance. You already know the force, which is 130 N. Simply multiply by two meters.

W = Fd = 130 N x 2.0 m = 260 J

Answer 3

Work = Force (N) x Distance moved (m). ( = Nm or Joules).

= 130N x 2m = 260 J.
