A driver in a car traveling at a speed of
70 km/h sees a cat 129 m away on the road.
How long will it take for the car to accelerate uniformly to a stop in exactly 125 m?
Answer in units of s

  • physics -

    The average speed, 35 km/h = 9.72 m/s, multiplied by the time, must equal 125 m.

    Use that fact to solve for the time.
