A gray kangaroo can bound across level ground with each jump carrying it 8.4 from the takeoff point. Typically the kangaroo leaves the ground at a 23 angle. What is its takeoff speed? What is its maximum height above the ground?
speed= you solve it in terms of t.
then vertical equation:
put what you solved for speed above into this equation, then solve for timeinair.
then solve for speed.
