Question

To reach a target represented by a square of 2 meters on thesides, where the center is at a distance D = 50 meters of the pointof release of the projectile (on the same horizontal), You use asling of length l = 0.6 m that you turn in a vertical perpendicularplan of the target, with a frequence of N turns per seconds. We release the projectile of mass m when the sling makes anangle with the vertical. To resolve this problem, we neglectthe resistance of the air. 1. Show that the trajectory of the projectile is the parabola: where v0 is the initial celerity of the projectile. 2. If = 30 degrees, what is the frequence N necessaryto reach the centre of the target? 3. Again with the same value of , find the frequencesNh and Nb that reaches the top and bottom of the target? (Nh = top , Nb = bottom ). 4. Find the angles H and B necessary to reach thetop and the bottom of the target when the frequence is maintainedat the calculated value of question 2.
