You are playing basketball and go to toss the ball to a teammate who is 10 m away. You throw it upward at an angle of 70 degrees and your teammate catches it at the top of their jump. Assume the ball and your teammate start at the same height, and your teammate jumps with an initial upward speed of 3.5 m/s. How fast must you throw the ball and how long must they delay their jump for the play to work? Show all steps: situation and variables, strategy, and all calculation steps(5 box solution).
