A Speedster car is traveling at a constant speed of 30m/s when it passes a stationary police car. one second after the car passes the police car
Start from rest and accelerates at a constant rate of 7,50 m/s to chase the speeding car. How long afterwards will the police
car catch up with the speeding car?

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
