Physics · Projectile Motion

A small ball is projected from the origin (0 m, 0 m) in the x-y plane at t = 0 s. Under constant gravity in the negative y-direction, its velocity vector at t = 1.0 s is vec(v) = 32i + 14j (in m/s). What is the total time of flight of the ball before it returns to the projection height? (take g = 10 m/s2)
