Is this statement true?
For a free fall object(the horizontal component of the initial velocity is zero), its velocity is zero when it reaches maximum height, but its acceleration is not zero at the same time.
Homework Answers
When an object is free fall under gravity than at maximum height object will have velocity zero.
But it has gravitational acceleration at every point in down word direction.
