Question: A gray kangaroo can bound across a flat stretch of ground with each jump carrying it 8.00m from the takeoff point.
Part I: If the kangaroo leaves the ground at a 20.0 degree angle, what is its takeoff speed?
Part II: What is its horizontal speed?
I need help to solve the above question and express your answer to three significant figures and include the appropriate units.
