Answer #1

when we apply breaks slightly break shoe of the car get in contact with the car tyres and produces frictional force but since pedal is pressed slightly so there is a relative motion between show an tyre and the frictional force produces is kinetic friction force.

similarily if we press pedal hardly break shoe presses more hardly and relative motion between shoe and tyre stops and now frictional force poduced is static friction force

we already know that static friction force > kinetic friction force

thus the car will stop with jerk.
