A car of mass 250 kg, is accelerated from rest by a net force of 400 N for 20 s. After this, the engine is switched off and the car slows to a halt, due to a net force of 100 N against its motion. What is the maximum velocity the car reaches and what is the total journey time, where the car is in motion?
