Two pucks are initially moving along a frictionless surface as shown in the diagram. The pucks have mass `m_(1)ltm_(2)` and begin with equal magnitude of momentum. A constant force `vec(F)` is applied to each puck direactly to the right for the same amount of non`-`zero time. After the pushes are complete, what is the relationship for the size of the moments of pucks (`p_(1)` and `p_(2)`) ?

A

`P_(1)ltP_(2)`

B

`P_(1)=P_(2)`

C

`P_(1)gtP_(2)`

D

More information about the masses, speeds, force and time are required to answer the question

Two blocks of mass m and 2m are kept on a smooth horizontal surface. Theya are connected by an ideal spring of force constant k. Initially the spring is unstretched. A constant force is applied to the heavier block in the direction shown in figure. Suppose at time t displacement of smaller block is x_(1) then displacement of the heavier block at this moment would be
