b) angle of projection:
find initial velocity components for i and j (let t=0)
and then draw a triangle and find tan x, and solve for x to get it
(bc the angle of projection is the direction of the velocity vector)

c) collision: when both x and y components r at the same place
so u would do xp + xq = 120
and yp = yq
and solve for T.
