**Henry**, Monday, June 18, 2012 at 3:31pm1. R = Xo * T = 200 m.

Xo*5 = 200

Xo = 40 m/s. = Hor. component of initial

velocity.

2. Tr = T/2 = 5 / 2 = 2.5 s.

Y = Yo + gt.

Yo = Y - gt = 0 - (-10)*2.5 = 25 m/s. =

Ver. component of initial velocity.

hmax = (Y^2-Yo^2)/2g.

hmax = (0-(25)^2) / -19.6 = 31.9 m.
