Answer 2

Answer:

25 m/s should be the answer which is not given in option

Explanation:

let the speed of the ball x m/s

if we take distance as given as 15m than

time = distance /speed = 15 / x seconds

Camera takes pictures at the rate of 10 per second

so in 15/x seconds it would take = 10(15/x) pictures

In the picture shown in question in 15 m distance the pictures taken by camera are 6

therefore

10(15/x) = 6

150 = 6x

x = 150÷6 = 25 m/s
