A block of mass 0.5kg on a horizontal surface is attached to a horizontal spring of negligible mass and spring constant 50N/m. The other end of the spring is attached to a wall, and there is negligible friction between the block and the horizontal surface. When the spring is unstretched, the block is located at x = 0m. The block is then pulled to x = 0.5m and released from rest so that the block-spring system oscillates between x = -0.5m and x = 0.5m, as shown in the figure. Which of the following claims is correct about the block’s period of oscillation? 1- The period would increase if the block were released from rest at x=0.8m.
2- The period would increase if the block had a mass of 1.2kg
3- The period would increase if the spring had a spring constant of 75 N/m
4- The period would increase if the block-spring system was oriented vertically so that the block-spring system oscillates between y = -0.5m and y = 0.5m , the mass of the block is 0.5kg, and the spring constant is 50 N/m.
