A bungee cord displays the idea of impulse and momentum well. The cord stretches to almost twice its length as it brings the jumper to a stop before hitting the ground. Explain how this stretching
lessens the force of stopping felt by the jumper.

please help!!

What the heck r u talkin bout? ?

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.
