Right I got that it was the y velocity, and I tried to find the x component and do the Pythagorean equation... but I'm seeing now that the easiest thing to do is to use the y velocity/sin 45 to get the right answer. Thanks.

Homework Statement A gazelle leaps over a 2.1m fence. Assuming a 45° takeoff angle, what is the minimum speed?Homework Equations 1. x=v0x * t 2. y = v0y * t - 1/2gt2 3. vy = v0y - gt 4. vy2 = v0y2 - 2gΔyThe Attempt at a Solution I assumed at the top of the leap, vy=0 m/s, so I used equation 4...
