(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball is thrown at a velocity of 10 m/s, at an angle of 30° from horizontal and released 2 m

above the ground. What will the magnitude of ball’s resultant velocity be at the moment of

impact with the ground?

2. Relevant equations

Vf2 = vi2 + 2as

3. The attempt at a solution

Vf2 = 5(2) + 2 x -9.8 x -2

Vf2 = 25 + 39.2

Then find the square root

The answer is 11.8 m/s

What am I doing wrong, please help

Thanks
