  • Dropping a ball and calculating its speed. | Physics Forums

    Aug 07, 2014· Not "speed" of gravity, acceleration due to gravity. If the acceleration is -9.8 m/s^2 then the speed after t seconds is v= 9.8t+ v0 (v0 is the initial speed and I am taking positive downward) and then the distance traveled is s= 4.8t^2+ v0t. Since the ball is "dropped" the initial speed is 0 so we have v= 9.8t and s= 4.8t^2.
