Speed at top of projectile is 8.0 mls % f: image source: ht! sJMwwamscoach/resourceson -'um -the-tecnnfcaI-modei a) Athletes rst run up to a take-off board and, without going past it, launch themselves into a sandpit at the same level at the take-off board. In one long jump practice, an athlete jumped a horizontal distance of 7.2 m. Her speed at the top of the projectile was measured to be 8.0 mfs. Ignoring the effects of air resistance and treating the jumper as a point object for simplicity, determine (in any order) i) duration of the whole ight t, ii) the initial take-off velocity 1? (in vector form), and iii) the launch angle, 9
