Astone is thrown vertically upward with an initial speed of 5 m/s. what is the velocity of the stone 3 seconds later?

Explanation:

The acceleration due to gravity is in the downward direction. This means that it will oppose the upward motion of the stone. This will cause the stone to stop and begin to fall. Therefore, the sign of the final velocity is negative, since it is in the downward direction. The final velocity is given by:

i need the answer to this too but idk it ; -;
