Im a 1st year physics student in the 11th grade. I haven't had much trouble with the assignment, but for some reason i cannot get the correct solution on this problem.
A certain car is capable of accelerating at a rate of 0.57 m/s2. How long does it take for this car to go from a speed of 53 m/h to a speed of 68 m/h? Anser in units of s.
I would assume that the correct kinematic equation to use would be v=v.+a(t) if .57 is the acceleration/ 53 is v./ and 68 is v..., but when I do that I get the wrong answer, if you could help and tell me what I am doing wrong I would appreciate it! =)
