A0.5 kg squirrel climbs a 75.0 m tall vertical maple tree. what must the squirrel’s average speed be in order to match the power output of a 100 w lightbulb?

Squirrel’s average speed = 277.78 m/s

Explanation:

Power of squirrel = 100 W

Mass of squirrel = 0.5 kg

Height climbed = 75 m

Potential energy = mgh = 0.5 x 9.81 x 75 = 367.875 J

We have

Substituting

So squirrel need to cover 75 m in 0.27 s

Speed required

Squirrel’s average speed = 277.78 m/s
