How do you measure speed of a basketball?

If you drop a basketball from a certain height without putting any force into it, how do you measure its speed?|||V = gt


or





V = sqrt(2gx)





where V is the speed; g = 9.8 m/s/s (the acceleration of the ball due to the force of gravity); t is the elapsed time and x is the distance fallen|||Everything falls at the same rate. The contributing factor is our atmosphere. Physics experiments put a feather and a rock in a vacuum chamber and release them at equal heights. They drop at the same speed.|||The basketball's speed changes all the time since it's accelerated by the force of gravity.





You can find the velocity at any given time using the formula: v=g*t, where g is the acceleration applied by gravity (something like 9.8) and t is the time in seconds from the release of the ball.





If you drop the ball from a certain height and would like to know its speed a moment before it hits the ground, measure the height (h) and use the following formula:





v^2 = 2*g*h.





For example: Let's say we drop the ball from a height of 10 meters.


v^2 = 2*9.8*10 = 196





So v = sqrt(196) = 14 m/s.|||haha i dont no what theyre even talking about


speed = distance / time


measure the distance = 10 m


time the fall = 2 secs


10 / 5 = 2


so the sped of the ball is going at 2 m/s


the others try and complicate it haha
