A softball player hits a ball at 78 miles per hour. Then she hits a ball at
80 miles per hour. Which is the best prediction? (1 point)
The ball hit at 80 miles per hour will have more kinetic energy.
The balls’ kinetic energies will depend on the distances they travel.
The ball hit at 78 miles per hour will have more kinetic energy.
The balls will have the same amount of kinetic energy.
80 miles per hour. Which is the best prediction? (1 point)
The ball hit at 80 miles per hour will have more kinetic energy.
The balls’ kinetic energies will depend on the distances they travel.

I agree
(1/2) m v^2 is bigger if v is bigger and m is the same

That's correct! The kinetic energy of an object is directly proportional to the square of its velocity, assuming the mass remains constant. Therefore, the ball hit at 80 miles per hour will have more kinetic energy than the one hit at 78 miles per hour.
