A projectile is shot from the edge of a cliff h = 125 m aboveground level with an initial speed of v0 = 155 m/s at an angle of37.0° with the horizontal.
(a) Determine the time taken by the projectile to hit point P atground level.
(b) Determine the range X of the projectile as measured from thebase of the cliff.
(c) At the instant just before the projectile hits point P, findthe horizontal and the vertical components of its velocity. (Takeup and to the right as positive directions.)
(d) What is the the magnitude of the velocity?
(e) What is the angle made by the velocity vector with thehorizontal?
(f) Find the maximum height above the cliff top reached by theprojectile.
This problem has me stuck. I thought I could use t = â(2h/g) tofind the time to hit the bottom, but it's not working out right.Any help? I don't just want an answer, but I really want tounderstand how to do it (for the test next week!) Thanks!
