Answer:

70 watts

Explanation:

Power  = W ork(in joules)/ time

Work= F orce x d istance

F  is the force exerted in newtons  

d  is the distance moved in meters

Work = 35N x 10m

         =350

P= 350 J/ 5 s

P= 70 watts

Answer:

The power used is 70 W.

Explanation:

The formula for power is:

P = W/t

Where:

P = Power in Watts (W)

W = Work in Joules (J)

t = Time in Seconds (s)

The formula for work is:

W = Fd

Where:

W = Work in Joules (J)

F = Force in Newtons (N)

d = Distance in Meters (m)

Determine the given values from the problem.

F = 35 N

d = 10 m

t = 5 s

Find work.

W = Fd

W = 35 N (10 m)

W = 350 J

Find power.

P = W/t

P = 350 J / 5 s

P = 70 W
