Question: A car traveling at 10. meters per second accelerates at the rate of 1.5 meters per second2 while traveling a distance of 600. meters. The final speed of the race car is approximately
(1 ) 1900 m/s
(2 ) 910 m/s
(3 ) 150 m/s
(4 ) 44 m/s

Answer 1
1900 m/s
INCORRECT
When you use the formula
to find the final velocity, the inital velocity is 10m/s, the acceleration is 1.5m/s2 and the distance os 600. meters, and if you put that into the equasion,you don't
get out 1900m/s. It looks as though you forgot to take the square root of your answer.return to top
Answer 2
910 m/s
INCORRECT
When you use the formula
to find the final velocity, the initial velocity is 10m/s, the acceleration is 1.5m/s2 and the distance is 600. meters, and if you put that into the equasion, you don't
get out 910m/s.
return to top Answer 3
150 m/s
INCORRECT
When you use the formula
to find the final velocity, the initial velocity is 10m/s, the acceleration is 1.5m/s2 and the distance is 600. meters, and if you put that information into the equasion,
you do not get 150m/s as your answer.
return to top Answer 4
44 m/s
CORRECT
Using the formula
to find the final velocity, the initial velocity is 10m/s, the acceleration is 1.5m/s2 and the distance is 600. meters. When you put that information into the equasion,
you end up getting 44m/s as the answer.
