An object is released from rest at a height of 100 meters above the ground. Neglecting frictional forces, the subsequent motion is governed by the initial-value problem

where y(t) denotes the displacement of the object from its initial position at time t . Solve this initial- value problem and use your solution to determine the time when the object hits the ground.
