Question1

Two cars drive on a straight highway. At time t=0, car 1 pass mile marker 0 travelling due east with a speed of 20m/s. At the same time, car 2 is 1km east of mile marker 0 travelling 30m/s west. Car 1 is speeding up with an acceleration of magnitude 2.5m/s, and car 2 is slowing down with an acceleration of magnitude 3.2m/s.

(a) Write x-versus-t equations of motion for both cars, taking east as the positive direction.

(b) At what time do the cars pass after that to one another?

Question2

Ann is driving down a street at 63 km/h. rapidly a child runs into the street. If it takes Ann 0.799 s to react and apply the brakes, how far will she have moved before she begins to slow down? Response in units of m
