2. At the instant shown, car A has a speed of 20 km/h downwards, which is being increased at a
rate of 250 km/h? as the car enters an expressway. At the same instant, car B is decelerating at
300 km/h? while traveling forward at 100 km/h. Determine the magnitude and direction of
velocity and acceleration of A with respect to B.

1.) Let sA = 15t^2 + 10t + 20 and sB= 5t^2 + 40t, where t ≥ 0, be the position functions of cars A and B, respectively, that are moving along parallel straight lanes of a highway (here, t is in minutes and s in feet). a.) At what instant of time do they have the same velocity? b.) Which car is ahead when the two cars have the same velocity? Please show your complete solution thanks.
