Astone is thrown down off a bridge with a veloctiy of 5.6m/s. what is the velocity afer 3 seconds have passed?

Final speed of the stone, v = 35 m/s

Explanation:

It is given that,

Initial speed of the stone, u = 5.6 m/s

Let v is the velocity of the stone after 3 seconds have passed. It is moving down under the action of gravity. So, using the first equation of motion as :

v = 35 m/s

So, the final speed of the stone is 35 m/s. Hence, this is the required solution.
