Question #f54e3

Answer 1

Yes, as stated, it is 12 x 5 = 60 Nm or 60 J

Explanation:

Work done = energy transferred = force x distance

Don’t worry about this bit if you haven’t got to it yet, but at higher levels this equation becomes a little more complex as the force and the distance moved are both vectors so the direction of both has an effect. In this case we consider the displacement, s instead of the distance and the angle between them, `theta` so the equation becomes:
`W = vec F.vec s. costheta`

Answer 2

60J

Explanation:

we use the Equation:
Work done = Force`*`distance

`12N*5m=60J`

Answer: 60 Joules
