A boy launched from a waterslide into the air at an angle of 49º. With no wind she would travel 430m horizontally where she lands in a pool. The time she is in the air is 2.9s.

-What is the magnitude of the velocity at landing?

-At maximum height he experiences a brief gust of wind that instantaneously reduces his horizontal velocity by 3.9m/s. What distance does she travel horizontally?

I have a physics problem that gives me a projectile launched. It tells me the angle above horizontal, the MINIMUM speed while in flight, and the amount of meters the ball traveled when it lands. The question asks for max height. What's tripping me up is this MINIMUM velocity. Where on the projectile is the velocity a minimum. I was thinking the minimum velocity would be at the highest point, because at the highest point the velocity is 0, however,...
