Calculate the power needed to raise 32lb. a distance of 12 feet in 4 seconds

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.

Power = gravitational potential energy / time

Gravitational potential energy = m g h

here m = mass

        g = gravity die to acceleration = 9.81 m/s²

        h = height

1 Ib = 0.453592 kg

32 Ib = 14.5 kg

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
