Im new here and I really dont know the standard sorry if this is too easy for you, There is a car moving at constant speed and suddenly the driver applies the brakes. So everyone in the car moves forward. But as the car holts the people go forward. Why? With reasons. I have a decent solution but I dont think its right. I thought it this way........... imagine the brakes are a force opposing the motion of the car so due to the 1st law the people will go forward. But after that to achieve equilibrium the car goes backwards. Do you think the answer is right?
