Question

The kinetic energy of a ball with the mass of 0.5 kg and a velocity of 10 m/s is what

Answer 1

Answer:

25J

Explanation:

Kinetic energy = 1/2 mv²

Mass = m= 0.5kg

Velocity = v = 10m/s

K. E = 1/2 x 0.5 x 10 x 10

K. E = 0.5 x 5 x 10

K. E = 2.5 x 10

K. E = 25 J

The S. I unit of energy is joules with symbol J
