Question
Please answer and explain the following question. Thank you
**Question 2:** A long jumper (Fig. 3.20) leaves the ground at an angle of 20.0° to the horizontal and at a speed of 11.0 m/s. (a) What is the speed of the jumper at the maximum height? (b) How long does it take for her to reach maximum height? --- **Image Description:** The image depicts a sequence of a long jumper in mid-air, demonstrating the different phases of the jump. The jumper progresses from the take-off, reaches maximum height, and begins descent. This visual represents the motion described in the problem, illustrating both the angle of take-off and trajectory.
