The line tic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is
tangare [24]

Answer: 25 joules

Explanation:

Recall that kinetic energy is the energy possessed by a moving object.

So, kinetic energy = 1/2 X Mass X Velocity^2

Mass = 0.5kg

Velocity = 10m/s^2

= 1/2 x 0.5kg x 10^2

= 0.5 x 0.5 x 100

= 25 Joules

Thus, the kinetic energy of the moving ball is 25 joules
