When a car is hit from behind, the occupants may experience whiplash. Use Newton’s laws of motion to explain what causes this result.
Solution 38DQ When a car is hit from behind, the car gets a motion along the direction of hit. The occupants’ lower body parts are in touch with the car. So, they tend to move with the car’s forward motion. But the heads of the occupants are not in motion and hence they tend to preserve their inertia of rest. So, heads will move backward and hit the seat or any other object that is right behind the heads. This is the reason why the occupants may experience a whiplash.
