Answer:

130.1 W

Step-by-step explanation:

Power is work or energy divided by time, so power has the units of joules/second, which is called the watt.

<h3>Formula</h3>

Power = gravitational potential energy / time

Gravitational potential energy = m g h

<em> g = gravity die to acceleration = 9.81 m/s²</em>

<em> h = height</em>

<em />

<h3>Conversion Ib to kg</h3>

1 Ib = 0.453592 kg

32 Ib = 14.5 kg

<h3>Conversion feet to m</h3>

1 feet = 0.3048 m

12 feet = 3.6576 m

Plug value in the formula

(14.5) (9.81) (3.6576)

520.3 J

520.3 / 4

130.1 W
