Question 10 If the brakes on a car can give the car a constant negative acceleration of 2k m/62 , where k is a positive constant. What is the greatest speed it may be going if it is necessary to be able to stop the car within 25 meters after the brakes are applied? (A 20 m/s B 25k2 m/s 10/k mls 5k m/s
