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
