Consider a person on the moon who launches herself into a standing broad jump at 45 degrees. The average force generated during launching is, as stated in the lecture delivered on march 7,2012, F=2W, and the distance over wich this force acts is 60cm. Kindly, compute:
(a) the range of the jump ;
(b) the maximum height of the jump ;
(c) the duration of the jump.
