The initial momentum before the collision of the first ball is 10 kg*m/s. The initial momentum before the collision of the second ball is negative 13 kg*m/s. The final momentum after the collision of the first ball is negative 8 kg*m/s. What is the final momentum after the collision of the second ball?

Where are the options ?

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.
