[SOLVED] Constant Acceleration 1. The problem statement, all variables and given/known data a. What constant acceleration, in SI units, must a car have to go from zero to 60 mph in 10s? b. What fraction of g is this? c. How far has the car traveled when it reaches 60 mph? Give your answer both in SI units and in feet. 2. Relevant equations 3. The attempt at a solution I have gotten answers for parts a and b, but I get really confused on part c. For a: 1 mph = .447 m/s, so 60(.447)=26.82 m/s. (26.82 m/s)/(10s)=2.68 m/s^2 For b: g=gravity=9.8 m/s^2. (2.68 m/s^2)/(9.8 m/s^2)=.273(100)=27.3% For c: I'm not sure where to start to find my answer. I appreciate any help! I just solved it! I've worked on part C for about 45 minutes to an hour. I just found an equation that worked, imagine that. For c: I used d=Vi(t)+0.5(a)(t^2) So, d=(0 m/s)(10 s)+0.5(2.68 m/s^2)(10^2)=134 m. Then to convert 134 m to feet = 134(39.37)=5,275.58 in/12=440 ft Hopefully this will help someone else out that is new to physics, like myself.
