In the vertical jump, an athlete starts from a crouch and jumps upward as high as possible. Even the best athletes spend little more than 1.00 s in the air (their ""hang time""). Treat the athlete as a particle and let [math]y_{\max }[/math] be his maximum height above the floor. To explain why he seems to hang in the air, calculate the ratio of the time he is above [math]y_{\max } / 2[/math] to the time it takes him to go from the floor to that height.

Using the same approach, determine the magnitude of the magnetic field based on the emf induced at frame 1000, as the loop is exiting the field. note: you need to measure the speed of the loop again–we suggest using a 60-frame interval centered around frame 1000.
