Solve the following second order differential equation:
An object that has a mass of m kg was thrown straight up from a platform which is h m above the ground. The initial velocity was
The air resistance is proportional to the velocity of the object and is equal to av N. Write down the equation for the distance traveled by the object at any time. Find the velocity of the object at the ground level for
