12. 2007: The figure below show two identical trollbys with loads A and B. The loads are identical in shape and size.
D
Given that the density of A is greater than that of B, explain why the
trolley in figure 3 (in) is more stable​

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.
