**1. A football is kicked at an angle of 45 degrees from a distance of 37 meters and just clears a 3 meter high goal on its way down. To the nearest m/s what was its initial speed?**

**2. v = v_0 + a*t**

v^2 = (v_0)^2 + 2a*(x - x_0)

x=x_0 + (v_0)t + (1/2)*a*t^2

v^2 = (v_0)^2 + 2a*(x - x_0)

x=x_0 + (v_0)t + (1/2)*a*t^2

**3. I set the original velocity as V and tried to solve but I got a negative number**
