If you are in a car at rest that gets hit from behind, you may suffer an injury to your neck called whiplash. Explain, in terms of Newton's First Law, how a car's headrest will help prevent whiplash.
Homework Answers
The passenger's head will remain at rest for the split second when the seat exerts a big force on the passenger's back causing a "whiplash" on your neck. This is an example of newton's first law because your head is not acted on by an unbalanced force while the rest of your body is. A head rest causes your head to accelerate with the rest of your body. If your head is on the head rest when receiving a rear-end collision, your head will move forward with the rest of your body. This will prevent whiplash

Problem 1. You hit a bowling ball with a mallet, starting from rest. Every time you hit it, its velocity increases by exactly 10 cm/s. You start timing (t 0 seconds) at the instant you hit the ball the first time, and you hit it once every second. Two simplifying approximations: (1) Suppose each hit is very short, so the speed changes in a short amount of time and (2) suppose the ball doesn't slow down between hits a. Att...

When you are a passenger in a car that makes a tight turn, your body seems to respond to the turn by moving towards the side of the car on the outside of the turn. Is a force acting on you that pushes you towards the outside of the curve? Explain. Consider the message of Newton's First Law in your answer. If your body stays relaxed as the vehicle you are in turns to the left, you will eventually contact...
