The car speeds up at a steady rate, moving toward the origin. In the 1989 Loma Prieta earthquake in California, approximately 2 million books fell off the shelves at the Stanford University library. A wooden billiard ball is thrown straight up with a velocity v 0 . Draw free-body diagrams for the forces acting on the projectile when it is part of the way up, at its highest point, and when it is part of the way down. Assume the air resistance is negligible.
Friction is so small that it can be ignored.
