Many car companies are performing research on collision avoidance systems. a small prototype applies engine braking that decelerates the vehicle according to the relationship a = − k √ t , where a and t are expressed in m/s² and seconds, respectively.
the vehicle is traveling at 20 m/s when its radar sensors detect a stationary obstacle. knowing that it takes the prototype vehicle 4 seconds to stop, determine; (a) expressions for its velocity and position as a function of time, (b) how far the vehicle traveled before it stopped.
