If two objects have the same mass which object has more kinetic energy? The object going faster or the object going slower

What is the measure of a change in an objects velocity?

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?

Aball with a mass of 1.5 kilograms is tied to the end of a rope. the ball is pulled to a height of 0.5 meters above the ground and released. the ball has joules of potential energy at position b. at position a, all of the energy changes to kinetic energy. the velocity of the ball at position a is meters/second. assume there’s no air resistance.
