Answer 2

AnsWer:-

The final velocity of the stone just before touching the ground is 19.6m/s.

Step-by-step explanation:

Given:-

• Initial velocity of the stone (u) = 9.8m/s².
• Value of the Gravity (g) = 9.8m/s².
• Height of the tower (h) = 19.6m

Need to find:

• The final velocity of the stone just before touching the ground.

SOLUTION:-

As we know that,

v² = u²+2gh

Putting values in this formula,

We get;

v² = 0²+2(9.8×19.6)

v² = 19.6×19.6

v² = (19.6)²

v = 19.6 m/s

Hence,the final velocity of the stone just before touching the ground is 19.6 m/s.
