Mylie Carey · Answer 1

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

Makenna Reilly · Answer 2

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
