A 2.0 kg mass is hanging from a spring. When it is in equilibrium, the spring is stretched 3.0 cm pasts its zero position. The mass and the spring are turned horizontally and hooded to a 5.0kg mass. Mass 1 is a wooden block with coefficient of static friction .58 and mass 2 is frictionless.
a. What is the mininimun amount of force that must be applied to mass 2 in order to make the system move?
b. How far will the spring be stretched from its zero position with this pulling force?
