Which of the following objects has the greatest kinetic energy? a baseball flying through the air at 90 miles per hour a baseball flying through the air at 45 miles per hour a baseball flying through the air at 20 miles per hour a baseball sitting on the ground

a baseball flying through the air at 90 miles per hour

Explanation:

As we know that kinetic energy is given as

so it depends on two factors

1) mass of object

2) speed of the object

so here for maximum kinetic energy we need to choose the one which will have maximum speed in all given options

So here we can say that maximum kinetic energy is given as

a baseball flying through the air at 90 miles per hour

as it is the maximum speed in all given options
