A boat can travel 2.60 m/s in still water.If the boat points its prow directly across a stream whose current is 1.10 m/s, what is the velocity (magnitude and direction) of the boat relative to the shore? What will be the position of the boat, relative to its point of origin, after 3.00 s?

Question

A boat can travel 2.60 m/s in still water.If the boat points its prow directly across a stream whose current is 1.10 m/s, what is the velocity (magnitude and direction) of the boat relative to the shore? What will be the position of the boat, relative to its point of origin, after 3.00 s?
a)displacement downstream
b)displacement across the river

velocity relative to shore? it is: Vbshore=Vriver +Vboat where Vriver is 1.1m/s downstream; Vboat is 2.60across.
