Answer:

150W

Step-by-step explanation:

Power = work done / time. The work done needs to be calculated first.

Work done = force × distance = 30N × 30m = 900J

Power = work done / time = 900J / 6s = 150W

Answer:

150 Watts

Step-by-step explanation:

Power=work/time

Work=Force times distance

Force = 30N

Distance = 30m

Time = 6 S

Work = (30N)(30m) = 900Nm

Power=900Nm/6s

Power=150 Watts
