Calculate the acceleration of a bus that goes from 57.6 km/h to a speed of 99.79 km/h in 10 s. (Hint our units are chosen to be descriptive and instructive so this time we will use km/h/s or km/hs since this allows us to see how much faster we will go each second and thus anticipate how fast we will be going if we are to continue to accelerate over a different period of time.)
