Question

Object displaced from 5 m height reaches ground at a distance of 10m. What is its final velocity?
A). 10 m/s
B). 10 √2 m/s
C). 20 m/s
D). 20 √2 m/s​

Answer 1

Answer:

ans. (A) 10 m/s

Explanation:

as v²-u²=2as

and initial velocity is 0

so v²=2as

=v²=2×10m/s²×5m

i.e v²=100m²/s²

so,. v= 10m/s

hence , final velocity= 10m/s ans.
