Answer 1

(A) You can read max y directly
(B) Use this equation for y - direction from y=0 to max y height and solve for Vi
\[V_f^2 = V_i^2 + 2a(Y_{final} - Y_{Initial})\]
(C)Use this equation for y-direction from y=0 to max height and solve for tf
\[A = \frac{Vf -Vi}{T_f - T_i}\]
(D) After finding the time to reach max height, use the time and the horizontal distance (x distance) to the max height point to find the horizontal velocity using the average velocity formula
(E) setup the initial velocity vector and components and solve angle using trig functions
