The stone's velocity just before it strikes the ground will be 79 meters/second.
Speed is distance divided by way of time. genuinely positioned, in case you drove 60 kilometers for one hour, it would appear to be this: speed = distance (60 km) / time (1 hour) = 60km/h.
the pace is a vector quantity that refers to "the rate at which an item changes its position." imagine a person shifting rapidly - one breakthrough and one step back - continually returning to the original beginning role. while this could result in a frenzy of hobby, it would bring about zero speed.
The acceleration of gravity near the earth is g = -9.eighty one m/s^2. To discover something's pace (or velocity) after a sure quantity of time, you just multiply the acceleration of gravity by way of the amount of time it was permitted to go off. so that you get: speed = -9.80 one m/s^2 * time, or V = gt.
