Question

A ball is droped from a
tower of height 30 meters. Find time taken to fall through this height


you should say with explanation​

Answer 1

Step-by-step explanation:

Here, s ( distance ) = 30 m

         a ( acceleration ) = 10 m / s ^2

         u ( initial velocity ) = 0 m / s

According to the equation,

s = ut + 1 / 2 at ^2

30 = 0 + 1 / 2 * 10t^2

30 = 5t^2

30 / 5 = t^2

t = $\sqrt{6}$ = 2.44 = 2.4 seconds

Hope this helps you !!!!
