A 0.145 kg baseball is thrown from a platform above the ground at a 10 m/s. The ball is moving 15 m/s when it strikes the ground. From what height above the ground was the ball thrown?

Respuesta :

Well let see, we don't have any information about the initial distance we have to use our logic

assuming that the distance moves from 1 to 2 m with initial speed , it means that the distance factor is 2

Since the initial speed has doubled, it would be very likely that the factor of the distance is MORE THAN 2 . Find the answer that either got 3 or 4 distance factor

hope this helps
