Final answer:
To reduce forces in a car crash, it is beneficial to redirect the path towards objects that will cause the car to stop over a greater distance. This can include hitting bushes instead of trees or using sand barrels placed in front of freeway abutments. By increasing the collision time, the force of impact can be reduced.
Step-by-step explanation:
In a car crash, the forces acting on the car and its occupants can be reduced by redirecting the path towards objects that will cause the car to stop over a greater distance. This is because a longer collision time means that the force on the car will be less. For example, hitting bushes rather than trees or sand barrels placed in front of freeway abutments can help reduce the forces involved in a crash. By increasing the time over which the force of impact acts, the force can be decreased.
