Explanation:
Tarzan swing can be thought of as change in potential energy by going from higher location We solve for height of beginning of the swing by using simple cosine equation:
So
ΔE=mg(h₂-h₁)
The potential energy of Tarzan initial position is converted into kinetic energy of his swing.By using kinetic equation
