An athlete competing in the long jump leaves the ground with a
speed of 9.14 m/s at an angle of 55degrees with the horizontal .
What is the length of the athlete's jump if air resistance is of no
significance ? A) 0.88m b) 8.0m c) 4.0m d) 12m e) 17m
time of flight = 2*9.14*sin55/9.8 = 1.524 sec
lenght = 9.14*cos55 * 1.524 = 8.010 m
