Question

a stone is released from the top of tower of height 19.6 m. calculate the final velocity just before touching the ground​

Answer 1

Answer:

Hope this will help you...!!!

Answer 2

Answer:

v = 19.6m/s

Explanation:

Given that

Initial velocity u = 0

Tower height = total distance = 19.6m

g = 9.8 m/s2

Find out , Final velocity just before touching the ground.

Solution:Let us solve using third equation of motion

v2 = u2 + 2gs

v2 = 0 + 2 × 9.8 × 19.6

v2 = 384.16

v = √(384.16)

v = 19.6m/s

Final velocity just before touching the ground = v = 19.6m/s
