An ideal spring (mspring= 0 kg) with k= 15.0 N/m holds a 0.75 m long rod (mrod = 3.5 kg) so that the rod is horizontal. The spring is attached to one of the rod's ends and the rod sits on a pivot located at x= 0.50 m away from the point where the spring is attached. What is the spring deformation if the system is in equilibrium? Consider g=9.80 m/s2. Question 2Select one: a. y = 0.27 m b. y = 0.44 m c. y = 0.48 m d. y = 0.57 m
