In a study kangaroos, one kangaroo could jump straight up to a height of 2.5 m. When moving forward, it left the ground with a velocity of 11.3 m/s at an angle of 27° above the horizontal. A)Sketch both types pf jumps, labeling axes and variables. Collect all known quantities. B)What speed does it need to leave the ground with to reach a height of 2.5 m if it jumps straight up? C)What are the x and y components of its velocity when it hopping forward? D)How long is it in the air for each forward hop? E)What is the horizontal distance traveled for each hop? F)How long would it take to hop 100 m?
