Refer to your lab guide and review the data in table f to complete each statement.
the mass of g1 at all times during this trial was
the velocity of g1 + g2 after the collision was
m/s.
the momentum of g1 after the collision was
kg. m/s.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
