Will give correct answer brainliest Automobile manufacturers, such as Nissan and Toyota, incorporate safety features into their vehicles. Crumple zones in the engine compartment and air bags are two examples of safety technology designed to protect driver and passengers involved in a collision. How do these design features impact the formula above and the force of impact? They decrease the force of impact by providing a cushion during the impact. Smaller force = lower momentum. They decrease the force of impact by extending the time it takes to stop the driver and passenger. Longer time = less force. It takes a longer time for the velocity of the vehicle to decrease, therefore the force is less. Decrease in velocity = less force. When a car rebounds it undergoes a greater change in velocity and the force is decreased. Lower force = greater change in velocity.
