An object is subjected to a force in the north-east direction. To balance this force, a second force should be applied in the direction

What happens when force is applied in the direction of motion?

In the given table, Column I shows masses of the objects, Column II shows the initial and final velocity of the object after force is applied on it and Column III shows the time span for which force is applied on the object. Conditions for a motorcar with the force of 6000 N applied in opposite direction of motion are :
