Neglecting air resistance, the motion of an object moving vertically near earth’s surfaceis determined by the acceleration due to gravity, which is approximately 9.8 m/s2.suppose an object is thrown vertically upward att= 0 with a velocity of 20 m/s fromthe edge of a cliff that is 200 m above a river.1. write initial value problem.2. find the the velocity of the object, fort≥0.3. find the position of the object, fort≥0.4. find the maximum height of the object above the river.
