This week in lab, we talked about using antidifferentiation to go from acceleration to velocity, then to position, of an object moving under gravitational force. We used the following second order differential equation: Ill/(t) : _g, where g is acceleration under gravity. 1. If a rock is thrown upward from a 100 meter cliff with initial velocity 10 meters per second, nd how long it takes to hit the ground at the bottom of the cliff. Recall that g = 9.8 meters per second per second
