A body is thrown vertically upward from ...

A body is thrown vertically upward from a point `A` 125 m above the ground. It goes up to a maximum height of 250 m above the ground and passes through `A` on its downward journey. The velocity of the body when it is at a height of 70 m above the ground is `(g=10 m//s^(2))`

A

20 m/s

B

50 m/s

C

60 m/s

D

80 m/s

Text Solution

Verified by Experts

The correct Answer is:
C
The body is freely falling from a height of 250 m. Its velocity at a height of 70 m from the ground means velocity of freely falling body after travelling 180 m.
`v = sqrt(2gh)`.
