do horizontal and vertical problems separately
v = g t velocity down
h = 0 + Vo t + (1/2) g t^2 height
so
height = 4.9 (2.6)^2
height = 33.1 meters (high all right)
U = horizontal speed = constant
d = u t = 2.8 * 2.6 = 7.28 meters away
v = g t velocity down
h = 0 + Vo t + (1/2) g t^2 height
so
height = 4.9 (2.6)^2
