KE = (1/2) (mass) (speed)²

KE = (1/2) (20 kg) (40 m/s)²

KE = (1/2) (20 kg) (1,600 m²/s²)

KE = (10 kg) (1,600 m²/s²)

KE = 16,000 Joules

Answer:

The total resistance of the circuit = 188ohms

Explanation:

potential difference = 25volts

For resistors in series, equivalent resistance

Rt = R1 + R2 + R3

Rt = 120 + 18 + 50

Rt = 188ohms

The total resistance of the circuit = 188ohms
