1. The problem statement, all variables and given/known data A projectile is launched from the origin a distance h above the earth's surface with an initial velocity having speed v_0 and direction Theta_0 with respect to horizontal x-axis. Obtain an integral expression for the distance s the projectile travels along its path until it hits the ground at y = -h. Evaluate all derivatives in the integrand but do not evaluate the integral. Express any non-givens in terms of the givens of the stated problem. 2. Relevant equations y-y_0 = V_0cos(theta)(t) - .5gt^2 x-x_0 = V_osin(theta)(t) - .5gt^2 3. The attempt at a solution I do not know where to start. I have solved projectile motion problems before, but not like this. I'm thinking I might need to use a line integral. But other than that, I really don't know how to even begin. Help?
