Answer 1

Explanation:

What is the final velocity of an object? The object falls freely under gravity from a height equal to 10 m.

Answer 2

Answer:

v=10√2m/s

Explanation:

u=0

a=g=10m/s*s

s=h=10m

by Newton's third law,

v^2=u^2+2×g×h

v^2=2×10×10 [ as u=0]

v^2=100×2

v=√100×2

v=10√2m/s

v=14.14m/s
