The acceleration of a race car as a function of time is a(t) = kt, where a is measured in meters per second squared, t is measured in seconds and k is a constant. If its velocity at t = 0 is 2 m/s, and it is 26 m/s at t = 2 s, what is the value of the constant, k? * 12 m/s^3 12 m/s^2 O 24 m/s^3 O 13 m/s^3
