The equation for a projectile's height versus time is h(t)=-16t^2+vt+h

Let's take the first derivative: h'(t) = -32t +v. The maximum height is obtained when h'(t) = 0: -32t = -v t = v/32 t = 130/32 = 4.0625 s

Dear Keshia Wilson. The first derivative of (-16t^2+vt+h) with respect to t is equal to (-32t+v).
Where did you get 32 from? On my paper height equal 2/
