Final answer:
The most likely outcome of an unrestrained driver striking a utility pole at 70 MPH is severe injuries to the driver. It is important to wear seat belts and practice safe driving habits to minimize the risk of injuries in such collisions.
Step-by-step explanation:
When an unrestrained driver strikes a utility pole while traveling at 70 MPH, the most likely outcome would be severe injuries to the driver. This is because the impact forces involved in such a collision can cause significant damage to the human body.
Upon impact, the car would experience a sudden deceleration, bringing it to a stop in a very short time. This rapid change in velocity would transfer a large amount of momentum to the driver's body, leading to severe injuries.
It is important for drivers to always wear seat belts and practice safe driving habits to minimize the risk of injuries in case of a collision.
