Question is a golf ball is dropped from a height of 78m assuming gravity is 9.8 m s, What is the velocity of the ball after the first 10m.(adsbygoogle = window.adsbygoogle || []).push({});

I assume the equation to use is [tex]v^2=u^2+2ax[/tex]

v = Final velocity

u = Initial Velocity

a = Acceleration

x = Displacement

So I plug in [tex]v^2 = 0+2(9.8ms)(10.0)[/tex]

Now according to the answer sheet V should be 14.0 m s but no matter how I plug this in I cant seem to get the right answer.

I think the problem is the way I am actually doing the math so if someone could perhaps step threw the maths so I can see where I went wrong.

Thanks for any help

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
