✓ An alert driver used brakes to avoid an accident when suddenly a person steps from behind parked car in the path of driver at distance 35 m, (f = 0.6). Can the driver avoids the accident if he drive at velocity of: a) 50 km/hr, b) 60 km/hr, c) 70 km/hr.
Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A sees and reacts very unwisely to the police car P. Car A is traveling at VA = 128 km/h as it passes P, but over the next 5.0 seconds, the car uniformly accelerates to 140 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.0 m/s² until a speed of 165 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. Answer: s= m
