The question as text
A vertical rod is fixed to the horizontal surface of a table, as shown in Fig. 3.1. rod spring surface of table Fig. 3.1 (not to scale) A spring of mass 7.5 g is able to slide along the full length of the rod. The spring is first pushed against the surface of the table so that it has an initial compression of 2.1 cm. The spring is then suddenly released so that it leaves the surface of the table with a kinetic energy of 0.048 J and then moves up the rod. Assume that the spring obeys Hooke’s law and that the initial elastic potential energy of the compressed spring is equal to the kinetic energy of the spring as it leaves the surface of the table. Air resistance is negligible.
