When brakes are applied, from where does the extra friction come into play to stop the bicycle? [2 MARKS]

When a car moves on a road, then the bottommost point is always at rest relative to the ground at that particular instant and since friction only opposes relative motion between two bodies then according to this there should be no friction acting on the bottommost point of the wheel. If this is the case then according to Newton's 1st law, the car should continue to move forever unless brakes are applied. But in reality this doesn't happen & as the accelerator is released the car moves for sometime & ultimately stops even though no brakes are applied. How is this possible?

Q. A car moving with speed u can be stopped in minimum distance x when brakes are applied. If the speed becomes n times, the minimum distance over which the car can stopped would take the value

Q. A car stops after

, what was the initial velocity of the car?

Q. A car is going with a linear momentum
