A car can accelerate uniformaly to 120 mi/h in 30 s. It is max braking rate cannot exceed 0.7g. What is the minimum time required to go 1/2 mile? Assume it begins and ends at rest. (Hint: a graph of velocity vs. tme can be helpful). I am a high school teacher and one of my students gave me this problem to solve. I have tried my best to solve it but no luck of getting it. Any help is appriciated.
