Question

4 multiple choice 2 points in a car accident, a seat belt helps prevent injuries by applying a force less than the force of the moving passenger greater than the force of the moving car in the same direction as the cars motion in the opposite direction of the passengers motion 5 multiple choice 2 points a ball is dropped from the top of a tall building. as the ball falls, the upward force of air resistance becomes equal to the downward pull of gravity. when these two forces become equal in magnitude, the ball will flatten due to the forces. fall at a constant speed. continue to speed up. slow to a stop.

Explanation:

• Question 4: When a car is in an accident, passengers tend to keep moving forward (due to inertia). A seat - belt applies a force in the opposite direction of the passenger’s motion to stop or slow their forward movement.
• Question 5: According to Newton's first law, when the net force acting on an object is zero (in this case, the upward force of air resistance equals the downward force of gravity), the object will move at a constant velocity.

Answer:

• Question 4: in the opposite direction of the passenger’s motion
• Question 5: fall at a constant speed
