An object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second2 in the direction of its motion for a distance of 5.0 meters. What is the final speed of the object?

Vi=4m/s

a=2.0m/s*s

d=5.0m

Vf=?

Vf©÷=Vi©÷+2ad

Vf©÷=(4m/s)©÷+ 2(2m/s©÷)(5m)

Vf©÷=16(m/s)©÷+ 20(m/s)©÷

Vf©÷=36(m/s)©÷

Vf=6m/s
