Question

After falling through the first h metres, a
freely falling body acquires velocity V'.
After falling through the next h metre,
velocity acquired by it would be​

Answer 1

Answer:

√2V'

Explanation:

After falling through the first h metres, a

freely falling body acquires velocity V'.

After falling through the next h metre,

velocity acquired by it would be​

Free Falling

=> Initial Velocity = 0

After Covering h meter velocity = V

Using formula V² - U² = 2aS

U = 0 V = V'  a = g  S = h

=> V'² = 2gh

After covering next h meter

=> h + h = 2h

=> V² = 2g(2h)

=> V² = 2 (2gh)

putting  V'² = 2gh

=> V² = 2(V')²

=> V = √2V'

After falling through Next h Meter Velocity would be √2V'
