Do you have a question to ask ?
Her speed was 7.27 meters per second
Convection Zone: Just beneath the photosphere, and extending inward to about 0.7 Rsun, is the convection zone. Energy generated in the core of the Sun moves outward through this layer by a boiling motion in which hot plasma rises, releases some of its energy, cools, and then sinks again.
Complete Question

Answer:
Part A
The velocity of Tarzan is 
Part B
The percentage loss of kinetic energy is %-loss
%
Part C
The speed would be exactly the same
Explanation:
From the question we are told that
The mass of Tarzan is 
The height of the cliff is 
From the law of conservation of energy

Where PE is the potential energy of Tarzan at the top of the cliff which is mathematically represented as

KE is the kinetic energy of Tarzan as he swings toward jane and is mathematically represented as

So

=> 
Substituting values

=> 

From the question we are told that the actual velocity of Tarzan is

The kinetic energy at the the velocity is mathematically represented as

Substituting values

The kinetic energy at
is

=> 
Now the percentage loss of kinetic energy is mathematically evaluated as
%-loss 
substituting values
%-loss 
%-loss
%
The mass of Tarzan does not affect the speed because looking at this equation

We see that the velocity of Tarzan is not dependent on the mass of Tarzan
