1. How quickly do objects accelerate in freefall on Earth, ignoring air resistance(make sure you include units)? In what direction is that acceleration?2. How fast will an object be falling downwards 3 seconds after being released?steYou throw the bal straightupward while standing at afixed position.*******3. If you throws an object straight up into the air and it reaches its zenith(highest point) after 2 secondsa) How long will it take for the ball to drop back down from its zenith to yourhand?
