A vertically moving object projectile reaches a maximum height of 50 meters above its starting position


What is the projectiles initial speed?
What is the height above the starting point at 3.3 seconds?

I have been overwelmed by all the kenimatic formulas and i'm not sure which one to use or even how to use some of them

Ok a hint...

What does the object have at the top that it didn't have at the bottom? Where did it get it from?

So, I assume that you are trying to use kinematic equations to solve the problem rather than energy concepts or some other method. Is this true? If so, can you state any specific kinematic equations that you think might be useful? Is the acceleration constant in this problem?
