## anonymous one year ago An object is dropped from a height of 25 meters. At what velocity will it hit the ground? a 7.0 m/s b 11 m/s c 22 m/s d 49 m/s e 70 m/s

c. 22m/s $\sqrt{2\times9.8\times25}$

2. Astrophysics

To find the final velocity for a falling object, we actually get it from total energy for a falling object, $v_f = \sqrt{2gh}$

3. shamim

We know the formula v^2=u^2+2*g*h

4. shamim

v=?

5. shamim

Given u=0 g=9.8m/s h=25m
