Question

1. according to newtons third law, which car will get a bigger force from the wall? explain your answer. 5. design a solution to reduce the force of the cars crashing into the wall as discussed in question 4. be sure to include all of the parts to the system and explain how your design relates to newtons third law.

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. When a car crashes into a wall, the force exerted by the car on the wall is equal to the force the wall exerts back on the car. To reduce the force of the car crashing into the wall, a solution could involve crumple - zones in the car. Crumple - zones are designed to deform during a collision, increasing the time of the impact. According to the impulse - momentum theorem ($J = F\Delta t=\Delta p$), increasing the time of impact $\Delta t$ for a given change in momentum $\Delta p$ reduces the average force $F$ exerted on the car and its occupants. This relates to Newton's Third Law as the forces between the car and the wall are still equal and opposite, but the design of the car changes how the forces are experienced.

Answer:

A solution could be to incorporate crumple - zones in the car. These zones increase the impact time during a collision. By the impulse - momentum theorem, this reduces the average force on the car and its occupants. According to Newton's Third Law, the forces between the car and the wall are equal and opposite, but the crumple - zone design changes how the forces are experienced.
