The equations of motion you have been using will apply here: ax = 0 Vx = vo cos Vx,0 x = (v cos 0)t + xo Vx,0 a = -g V = vo sin - gt Vy,0 y gt + Yo 2 1 y = (v sino) t gt. Vy,0 Where is the launch angle measured relative to the horizontal and (x,y) are the coordinates of the projectiel at time t = 0. (1.1)
