Problem 12–85 The catapult is used to launch a ball such that it strikes the wall of the building at the maximum height of its trajectory. If it takes time t, to travel from A to B, determine the velocity v, at which it was launched, the angle of release 0 , and the height h. Given: a = 1 m b = 5.4 m tj = 1.5 s g = 9.81 Solution: A = 1 - e = 1 h = 1 m Guesses deg vĄ cos (8 )t, = b vĄ sin(e ) – g4, = 0 Given 1 a+ vsia(@ )t, - z817 = / El
