A moving walkway at the airport moves a 120Kg person 35m in 150s. How much power did this require?
Alexxx [7]

The amount of power required to move the 120 Kg person to a distance of 35 m in 150 s is 274.4 W

<h3>How to determin the power</h3>

Power is simply defined as the rate at which work is done. It can be expressed mathematically as

Power (P) = work (W) / time (t)

But

Work = force (F) × distance (d)

Therefore,

P = Fd / t

With the above formula, we can obtain the power as follow:

  • Mass (m) = 120 Kg
  • Distance (d) = 35 m
  • Time (t) = 150 s
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Force (F) = mg = 120 × 9.8 = 1176 N
  • Power (P) = ?

P = Fd / t

P = (1176 × 35) / 150

P = 41160 / 150

P = 274.4 W

Thus, the power is 274.4 W
