## Homework Statement

A river flows due north with a speed of 2.90 m/s. A man rows a boat and reaches the opposite shore right across its initial position; his velocity relative to the water is 5.50m/s. His landing point is due east relative to its initial location. The river is 1000 m wide

**.**

**a). What is his speed relative to the earth?**

b.) At what angle does he travel relative to the eastern direction?

c.) At what angle does he aim the boat relative to the eastern direction?

d.) How much time is required to cross the river?

e.) How far north of his starting point will he reach the opposite bank?

b.) At what angle does he travel relative to the eastern direction?

c.) At what angle does he aim the boat relative to the eastern direction?

d.) How much time is required to cross the river?

e.) How far north of his starting point will he reach the opposite bank?

^{2}=Vbr

^{2}+Vrg

^{2}

t=ΔX/Vbr

Distance=Speedavg x t

## The Attempt at a Solution

[/B]I had a similar problem before this one but this specifies that he reached the opposite shore right across from his initial position which is throwing me off.a.) 5.5

^{2}+2.9

^{2}=√38.66 -> 6.22 m/s

b.) Wasn't sure how to even do this for this question

c.) ^ ditto

d.) t=1000/5.5= 181.82 s

e.) Distance= 2.9 x 181.52 s = 527.28 m

Unfortunately those were all wrong :(
