Faraday's law Helps us to Find EMF

no of turns be N

\\ \bull\tt\longmapsto EMF=-N\dfrac{\Delta \Phi}{\Delta t}

Or

\\ \bull\tt\longmapsto \epsilon=-N\dfrac{d\Phi}{dt}

EMF is electromagnetic force

an Olympic runner leaps over a hurdle.if the runner initial vertical speed is 2.2m/s how much will the runners center of mass be
Snowcat [4.5K]
Supposing the runner is condensed to a point and moves upward at 2.2 m/s.
It takes a time = 2.2/g = 2.2/9.8 = 0.22 seconds to increase to max height. 
Now looking at this condition in opposite - that is the runner is at max height and drops back to earth in 0.22 s (symmetry of this kind of motion). 
From what height does any object take 0.22 s to fall to earth (supposing there is no air friction)? 
d = 1/2gt²= (0.5)(9.8)(0.22)²= 0.24 m
