Question

2. A stone is dropped from the top of a tower and allowed to travel freely under gravity. What is the initial velocity of the stone?​

Answer 1

Answer:

Given, a=g=10m/s

2

t=4s

u=0m/s {Initial velocity at rest}

So, height= ut+

(10)(16)

=80m

∴ Height of the tower= 80m

Answer 2

Answer:

➡The initial velocity of stone is 0(zero).

✅A stone is dropped from the top of a tower and allowed to travel freely under gravity . During free falling of a body the initial velocity of a body is zero.
