Physics Review Question Unit: Mechanics Year: 1996 Question#: 6 Question: A car traveling at 10. meters per second accelerates at the rate of 1.5 meters per second^{2} 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 What is this question really asking? Explanation by: Nicole J [ Return to question menu ] 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/s^{2} 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/s^{2} 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/s^{2} 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/s^{2} and the distance is 600. meters. When you put that information into the equasion, you end up getting 44m/s as the answer. return to top What's this question really asking? What is the final velocity of a car traveling 10m/s, accelerates at 1.5m/s^{2} and traveling a distance of 600. meters? return to top |
