Answer:

v=16.234m/s

Explanation:

Given data

Distance S=6.10 m

Initial Speed u=12.0 m/s

To find

Final Speed v

Solution

From third equation of motion we know that:

v^{2}-u^{2}=2aS

where

v is final velocity

u is initial velocity

a is acceleration

S is distance

Substitute the given values to find v

v^{2}=u^{2}+2aS\\v^{2}=(12.0m/s)^{2} +2(9.8m/s^{2} )(6.10m)\\v^{2}=263.56\\  v=\sqrt{263.56}\\ v=16.234m/s
