A mass m=2.0 is connected to a massless spring of force constant k_1=100N/m. This spring is connected at point P to a second spring, also massless, which has force constant k_2=200 N/m
A) if the mass is moved 2cm to the right of its equilibrium position, what is the net force on point P?
B) if the mass is moved 2cm to the right of its equilibrium position, how much does spring #1 stretch?
C) if the mass in moved 2cm to the right of its equilibrium position, what forces acts on the mass?
