Hi , a class 2 lever has the load between the force and the fulcrum .So a stapler is a good example.
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
