## Homework Statement

a ball is launched vertically from a spring loaded pipe at ground level, and it lands in 4.7 seconds. We need to figure out the launch velocity and how far the ball will land if fired at 45 deg angle.

## Homework Equations

I am using the following formulas, not sure if they are the correct ones to use.

V= -1/2gt

dy= Voyt + 1/2ayt (squared)

dx = Voxt + 1/2axt(squared)

## The Attempt at a Solution

I calculated the launch velocity to be 23m/s

however I am having trouble calculating how far the ball lands if launched at 45deg angle.

The answer should be between 50-60 meters but I get an answer of 155.

Could someone please help me figure this out, please show work so I can understand. Thanks
