Question

A stone is dropped from a height of 100 metre.
Calculate its speed while striking the ground.​

Answer 1

Answer:

Step-by-step explanation:

2gH=v^2-u^2

2×10×100=v^2-0^2

=>2000=v^2

=>44.72m/s

Answer 2

Answer:

Step-by-step explanation:

Taking g as 10 m/s

Using third equation of motion

v^2-u^2=2gs

U is zero

v^2-0=2*10*100

v = 20root5
