Question

A basketball hoop is 2.90m above the ground. Lee is 1.96m tall, and the maximum vertical distance between the tip of his hands and the bottom of his feet is 2.81m. To dunk a basketball, the tip of his hands must be at 0.190m above the basketball hoop or more.

Question1: What minimum vertical distance in m must Lee jump so that he dunks a basketball?

Question2:If Lee jumped the vertical distance from the first part, with what vertical speed must he jump in m/s?

Question3: If Lee jumped the vertical distance from the first path, how long would it take for him to reach that vertical distance in s?

Answer 1

Answer:

1)0.9m

2) speed won't matter, he just needs to reach the height.

3)maybe 2 seconds, it can be calculated if we know his weight

Step-by-step explanation:

1) the difference between the height at which the basketball hoop lies and the tip of Lee's hands has been calculated here.
