The driver drives at a fixed speed (v = 30.0m / s), and detects a police officer on a stationary motorcycle. The police officer starts when the driver of the car is 100m ahead of the police officer. The police officer gives everything to the bottom and travels at a fixed acceleration (a = 5, 00m / s2) after the driver.


a) After how long does the police officer reach the driver?

b) What is the speed of the police officer at this point in km / h?
