Expanding gives:

hence in H.P.

Okay.
Thanks for the problem, I could not have found it otherwise.
Now I can simply use that program as a template for any series I meet!

Hi,

Thanks!
What transform did you apply?

Yes!
And I thought the initial velocity given was redundant there.
I think the equation was given to obtain the value of 'a', to indirectly say that the ball is thrown on earth-like planet!

Since velocity is (displacement) / (time taken), we need to use differentiation, not integration.

Suppose we don't know differentiation too, then we need to obtain the answer by putting in actual numerics.

Then we can make out that the answer approaches 8.4 m/s.
