Answer 1

Hi mate here is the answer:-✍️✍️✍️

Question:

A stone is released from the top of a tower of height 19.6 m. Calculate its final velocity just before touching the ground.

Answer:

Given,

Given,Initial velocity, u = 0

Final velocity, v =?

Acceleration due to gravity, g = 9.8 m/s2

Height, h = 19.6 m

We know that,

v2 = u2 + 2gh

= (0)2 + 2 × 9.8 × 19.6

= 19.6 × 19.6

= (19.6)2

= 19.6 m/s

Therefore, its final velocity just before

touching the ground is 19.6 m/s.

Hope it helps you ❣️☑️☑️☑️
