Question

Four balls, each of mass 0.300 kg. are connected by four identical springs, with spring constants k = 138 Nm. At t=0, the balls are simultaneously given equal initial speeds v = 1.00 m/s directed away from the centre of symmetry of the system. The springs are initially at their equilibrium length, x0 = 0.120 m. Select true or false for the statements below: e.g.. if the first statement is true and the rest false. enter TFFFF. i. In the initial configuration of the system at =0. the kinetic energy is zero. ii. As the balls reach then- maximum displacement, the spring potential energy reaches a maximum iii. In the initial configuration of the system, the spring potential energy is a minimum. iv. The distance moved by any ball is proportional to the change in length of any spring. The proportionality constant can be determined by geometry. v. As the balls reach then- maximum displacement. their kinetic energy reaches zero.
