Question

A baseball player throws a baseball straight up into the air, the ball leaving his hand at time t = 0.0 s. The ball reaches maximum height at t = 1.4 s. When will the baseball return to the height from which it was released?

Answer 1

The ball should take twice as long to return to its original position as it took to reach its maximum height, so it should return to its original position at $t=2.8\,\rm s$.
