2. 1D Motion / Kinematics

A sports car moving at constant velocity travels 120 m in 5.0 s. If it then brakes and comes to a stop in 3.7 s, what is the magnitude of its acceleration (assumed constant) in m/s², and in g's (g = 9.80 m/s²) ?

The position of an object is given by 𝓍 = At + Bt², where 𝓍 is in meters and t is in seconds.                                                                                                         

(b) What is the acceleration as a function of time?"
