2.57 joule energy lose in the bounce .
<u>Explanation</u>:
when ball is the height of 1.37 m from the ground it has some gravitational potential energy with respect to hits the ground
Formula for gravitational potential energy given by
Potential Energy = mgh
Where ,
m = mass
g = acceleration due to gravity
h = height
Potential energy when ball hits the ground
m= 0.375 kg
h = 1.37 m
g = 9.8 m/s²
Potential Energy = 5.03 joule
Potential energy when ball bounces up again
h= 0.67 m
Potential Energy = 2.46 joule
Energy loss = 5.03 - 2.46 = 2.57 joule
2.57 joule energy lose in the bounce
To solve this we are going to use the formula for work: 
where
is the work done
is the force
is the distance
Scenario A. We know for our problem that
and 
. Lets replace those values in our formula to find :
Scenario B. We know for our problem that
and 
. Lest replace those value in our formula:
Scenario C. We know for our problem that
and 
. Lets replace the values in our formula:
We can conclude that:
- The scenario that requires the most work is C.
- The scenario that requires the least work is A.
