Answer:
675 joule
Explanation:
mass of the branch=15 kg
gravity=9. 8 m/s^2
height=4. 5 m
now,
potential energy=mass×gravity×height
=15kg ×9. 8 m/s^2 ×4. 5 m
=675 j
Answer: PE = 662 J
Explanation: Potential Energy is the product of mass, gravity and height.
PE = mgh
= 15 kg x 9.8 m/s² x 4.5 m
= 662 J
