Following the collision with a tree, the car rapidly decelerates and comes to a full stop in 0.26 seconds. Given that the passenger in the car has a mass of 70.0 kg and experiences a restraining force from the seat belt amounting to 4038 N, what was the car's initial velocity just before the impact with the tree?

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
