Question

If a ball takes 12 seconds to hit the ground, how fast was it falling when it hit the ground?

Answer 1

Roughly around 117.6 mph

Step-by-step explanation

To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards.
