Answer: 266.7 Mm/s
Explanation:
Time: 2.5 hours in seconds = 2.5 × 60 × 60 = 9,000s.
Distance: 75 KM converted to meters = 75 × 1,000 = 75,000m
Force: 32N
Power = work ÷ time
Work = force × distance
Work = 32N × 75,000m = 2,400,000 Nm
Power = work ÷ time
Power = 2,400,000 Nm ÷ 9,000s
Power = 266.7 Nm/s
