Question

The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s isJ.

Answer 1

My answer -

The formula for calculating kinetic  energy (KE) is KE = 0.5 x mv2. Here m stands for mass, the measure of how much matter is in an object, and v stands for velocity of the object, or the rate at which the object changes its position.
Hope i helped
