musickatia [10]

Answer:

The complete program is as follows:

m_str = input('Input m: ')

mass = float(m_str)

e = mass * 300000000**2

print("e = ",e)

Explanation:

This is an unchanged part of the program

m_str = input('Input m: ')

This converts m_str to float

mass = float(m_str)

This calculates the energy, e

e = mass * 300000000**2

This is an unchanged part of the program

print("e = ",e)
