Problem 7: A small ball bearing is released from rest in a tank of oil. The downward acceleration of the ball bearing is g - kv, where g is the constant acceleration due to gravity, k is a constant that depends on the viscosity of the oil, and v is the downward velocity of the object. Derive expressions for the velocity v and the vertical drop y as function of the time t after the ball bearings release.
