A car traveling at 150 mi/hr strikes a wall and bounces backwards at 30 mi/hr. If the car is in contact with the wall for 0.1 seconds, what is the force that the car exerts on the driver?
What is the force that the car exerts on the driver?
In summary, a car traveling at 150 mi/hr strikes a wall and bounces backwards at 30 mi/hr. The car is in contact with the wall for 0.1 seconds and the force that the car exerts on the driver can be calculated using Newton's second law, which states that force equals the rate of change of momentum.

Hi smh745! 
(i think it means average force)
Hint: use the full version of good ol' Newton's second law … force = rate of change of momentum

1. What is the force that the car exerts on the driver?
The force that the car exerts on the driver is known as the "centripetal force". This force is directed towards the center of the circular motion of the car and is responsible for keeping the driver in a curved path.
2. Is the force that the car exerts on the driver constant?
No, the force that the car exerts on the driver is not constant. As the car moves in a circular path, the direction of the force changes constantly, resulting in a continuously changing force on the driver.
3. How does the speed of the car affect the force on the driver?
The speed of the car has a direct effect on the force exerted on the driver. As the speed increases, the centripetal force also increases, making it more difficult for the driver to maintain control of the car.
4. What factors determine the amount of force that the car exerts on the driver?
The force that the car exerts on the driver is determined by the mass of the car, the speed of the car, and the radius of the circular path that the car is traveling on. These factors all contribute to the magnitude of the centripetal force.
5. Can the force that the car exerts on the driver be dangerous?
Yes, the force that the car exerts on the driver can be dangerous, especially at high speeds. If the driver is not able to handle the force properly, it can lead to loss of control of the car and potential accidents. It is important for drivers to understand and be aware of this force while driving.
