  3. ... for t and then double it (up then down). I'll leave that for you if you're interested. iii) Now I think we WILL need to find the maximum height. H = h0 + v² / 2g = 3m + (25m/s)² / 19...

  5. d = (1/2)(a)(t^2) = 10.80 = (1/2)(9.81)(t^2). Time to hit the ground, t = 1.48 s. Horizontally, d = vt. v = d / t = 3.9 / 1.48 = 2.63 m/s.
