Find the kinetic energy of a ball moving at 45 m/s with a mass of 0.18kg
mamaluj [8]

Answer:182.25 joules

Explanation:

Mass=0.18kg

Velocity=45m/s

Kinetic energy=(mass x(velocity)^2)➗2

Kinetic energy=(0.18 x 45^2) ➗ 2

Kinetic energy=(0.18x45x45) ➗ 2

Kinetic energy=364.5 ➗ 2

Kinetic energy=182.25

Kinetic energy=182.25 joules
