Question

friend please jaldi batao correct answer​

Answer 1

Answer:

I think the correct answer is c) v^2/g

but I think all the options are wrong bcz in question it is given height 'h' not gravitational 'g' and the ball throw vertically cannot be calculate in g it should be in h

so, your correct answer should be v^2/h

hope it helps you

Answer 2

The body that is thrown vertically upward with velocity u will have final velocity u=0 at the greatest height h.

Substituting the given values in the third equation of motion, u²=v²+2as

we have 0=v²−2gh. (taking g in the upward direction)

or h= v²

2g

:.option (b) is correct
