Question

A body falling freely covers a displacement of 2.5 m. It's velocity is​

Answer 1

Using v^ 2 = u^2+ 2as

as object is falling from a height so u= 0

this implies u^2 = 0

and a = 9.8 m/s^2 ( acceleration due to gravity)

Now,

v^2= 2as

v^2=2 ×9.8×2.5

v^2=49

v= 7 m/s

hope l help you

have a nice day
