Question

Two bodies of masses 4kg and 10kg are at rest. The ratio of times for which the same force must act on them to produce the same kinetic energy in both of them is 1) 1:4 2) 2:1 3) 1:2 4) 4:1 6: A block of mass 'm' is connected to one end of a spring of 'spring constant' k. The other end of the spring is fixed to a rigid support. The mass is released slowly so that the total energy of the system is then constituted by only the notential anarmu 66​
