Well the horizontal component of the initial velocity is 6.2, as given. I found the time (t) to be 2.578866342. Then I found Vy using Vy= gt + Viy, Vy = -15.35081607. Then I plugged my answer into a^2 + b^2 = c^2, Vy^2 + Vx^2 = V^2. -15.35081607^2 + 6.2^2 = V^2. ended with -16.55558981. answer...

Bump: Any help here?
