Disk Moving Doubled

APPH12-GJSNCW

A disk of mass $m$ strikes a similarly sized disk at rest on a frictionless table.

What conclusions can be drawn if the mass of the moving disk were doubled while the motionless disk remained the same?

A

The total kinetic energy and linear momentum of the system would be increased.

B

The total linear momentum of the system would increase but not the kinetic energy.

C

The total kinetic energy of the system would increase but not the linear momentum.

D

The total kinetic energy and linear momentum of the system would remain the same.
