how much power is used if a force of 35 Newtons is used to push a box a distance of 10 meters in 5 seconds

Power is found through the equation,

P

=

W

t

W

is the work done in joules

t

is the time taken in seconds

Work done is given by the equation,

W

=

F

⋅

d

F

is the force exerted in newtons

d

is the distance moved in meters

And so, the work done is:

W

=

35

N

⋅

10

m

=

350

J

Therefore, the power used up is:

P

=

350

J

5

s

=

70 W
