Apotato is fired from a spud gun at a height of 3m and an initial velocity of 25 meters per second, write the equation of this potato projectile. how high does the potato reach and at what time does this occur?

Check the picture below, the height there uses feet, but nevermind that, we can simply let it be meters, like in this case.



how hight does it go?  well, that'd be the y-coordinate of the vertex.

how long does it take?  well, that'd be the x-coordinate of the vertex.
