4. A spring is attached at a surface floor and a two-kilogram object is attached to its end. A boy applies eight newtons to the system and the object displaced twenty centimeters to its side. The system was considered to be a simple harmonic motion when the object was released. Find a) the spring constant and b) the period with which the ball will vibrate back and forth.
