With horizontal distance, initial velocity and angles problem?
17. recall that the equation for the horizontal distance h in feet of a projectile with initial velocity v0 and initial angle theta is given by h=v0^2/16 sin theta cos theta.

a. assume the initial velocity is 60 feet/second . what initial angle will you need to ensure that the horizontal distance will be exactly 100 feet?

b. assume the initial velocity is 60 feet/second. what is the maximum horizontal distance possible and at what angle does this occur?
