Use the equation v = v0 + gt = 0 + 9.80665 * 8 to find the final free fall speed (right before impact with the ground), which is 78.45 m/s.

To determine the velocity at impact, multiply the time by the acceleration caused by gravity. If the object hits the ground after 9.9 seconds, its velocity is

=(1.01 s)*(9.8 m/s2),

=9.9 m/s.

Initial velocity plus two times the acceleration times the distance equals final velocity. V is the speed right before collision. Initial velocity, or u, is 0 mph.

Gravity's acceleration, a, is 9.81 m/s/s.

Therefore, from the moment the projectile is thrown, through its highest point, and until just before it hits the ground, its acceleration is equal to the acceleration caused by gravity, or 9.81 meters per second per second.
