# Python code to apply the theorem of kinetic energy

# Function to calculate work and kinetic energy
# Work-Energy theorem: W = delta_Ek
def apply_kinetic_energy_theorem(mass, initial_velocity, final_velocity):
    # Initial kinetic energy
    initial_kinetic_energy = 0.5 * mass * initial_velocity ** 2

    # Final kinetic energy
    final_kinetic_energy = 0.5 * mass * final_velocity ** 2

    # Work done (change in kinetic energy)
    work_done = final_kinetic_energy - initial_kinetic_energy

    return initial_kinetic_energy, final_kinetic_energy, work_done

# Example usage
# Inputs
mass = 1.5  # mass in kg
initial_velocity = 2.0  # initial velocity in m/s
final_velocity = 5.0  # final velocity in m/s

# Apply the theorem
initial_kinetic_energy, final_kinetic_energy, work_done = apply_kinetic_energy_theorem(mass, initial_velocity, final_velocity)

# Output results
print("Initial kinetic energy:", initial_kinetic_energy, "J")
print("Final kinetic energy:", final_kinetic_energy, "J")
print("Work done:", work_done, "J")
