A "superman" is sitting on a tree 98 m high with a child he has rescued from the claws of a tiger. Unfortunately, the child slips and falls with an initial velocity of zero. The "superman" realized what was happening 2 seconds later and flew to catch the child at a constant speed of 39.2 m s-1. Calculate

A "superman" is sitting on a tree 98 m high with a child he has rescued from the claws of a tiger. Unfortunately, the child slips and falls with an initial velocity of zero. The "superman" realized what was happening 2 seconds later and flew to catch the child at a constant speed of 39.2 m s-1. Calculate :
a) the time the "super man" will fly before catching the child.
b) the distance the "super man" will fly to catch the child.
Assume that the acceleration due to gravity, g = 9.8 m s-2.
