calculate the potential energy of a 40 g (0.040 kg) sparrow resting on a branch 30 feet (9.15m) above the ground

Answer 1

To calculate the potential energy of the sparrow, we can use the formula:

Potential Energy = mass × gravity × height

Given:
Mass of the sparrow = 0.040 kg
Height of the branch above the ground = 9.15 m

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Potential Energy = 0.040 kg × 9.8 m/s² × 9.15 m
Potential Energy = 3.564 Nm or 3.564 Joules (rounded to three decimal places)

Therefore, the potential energy of the sparrow resting on a branch 30 feet above the ground is approximately 3.564 Joules.
