A vertical scale on a spring balance reads from 0 to 200 / rm{N}. The scale has a length of 10.0 / rm{cm} from the 0 to 200 / rm{N} reading. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.05 / rm{Hz}.
Ignoring the mass of the spring, what is the mass m of the fish?

A car of mass 1800 kg collides with a truck of mass 5200 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. The car's velocity just before the collision was m/s, and the truck's velocity just before the collision was m/s. Use the concept of the center-of-momentum reference frame.
