Answer 1

Answer:

Solution

The work done by the force is

WF = F d cosθ

But the force and displacement are parallel; the angle between them is zero.

Therefore WF = F d = 3.5 x 4= 14 J

Answer 2

Answer:

Work Done = W

force = F

Distance = d

W = Fd

or W = F*d

W (in joules) = 3.5*4 = 14 Nm (or J)

1Nm = 1J

so newton meters and joules are the same

Power = Work (in joules) /time (in seconds)

i don’t know the time so i can’t solve it
