Step 1
1) The driver drives the bus at a constant speed. During this time Lucy has no problem to keep her balance. According to Newton's first law of motion, there will be no force acting on her.
Correct answer is (b). This is because a body under constant motion remains in constant motion, until some external force is applied to change its position.
