Not a literal twist! It's just a bit more complex. 1. The problem statement, all variables and given/known data A ball is to be shot from level ground toward a wall at a distance "x". I am given the graph of the y component of velocity just as it would reach the wall, as a function of that distance x(m). Here's the equation of the line:y=-.5x+5, [0, 20] What is the launch angle? 2. Relevant equations v = vo +at x = xo + Vot + .5at2 v2 = (vo)2 + 2a(x - xo) 3. The attempt at a solution So I wrote out all I knew about the x and y components y: vo = 5, a = -9.8, xo = 0 x: a=0 I attempted to created a triangle of the horizantal and vertical components of velocity and the initial velocity as the hypotenuse solve with trig. I got sin(θ)= (5)/(V) tan(θ)= (5)/(vox) No help. I really am stuck! Using kinematics, you cant find the initial velocity because you don't know the time. You can't find the time, because you don't know where in the 20 m of the trajectory the ball hit the wall (according to my interpretation of the problem) Ah! If you could help I would be so grateful!! Thank you so much!!!
