Question

I wasn't able to get the answers for this problem, can someplease get the answers and explain how they got them? I will ratevery well, thanks!
A river flows due east at 1.80 m/s. A boatcrosses the river from the south shore to the north shore bymaintaining a constant velocity of 15.0m/s due north relative to the water. (a) What is the velocity of the boat relativeto shore?
1 m/s
2° (north of east)

(b) If the river is 290 m wide, how fardownstream has the boat moved by the time it reaches the northshore?
3 m I wasn't able to get the answers for this problem, can someplease get the answers and explain how they got them? I will ratevery well, thanks!

(b) If the river is 290 m wide, how fardownstream has the boat moved by the time it reaches the northshore?
3 m

Explanation / Answer

(a) . velocity of the boat relative to shore v =[ 1.8 ^ 2 + 15 ^ 2 ]                                                                 = 15.107 m / s (2). tan = 15 / 1.8             = 83.157 degrees (b). tan = required distance / width of river So, required distance = width of river * tan                                 = 290 m * tan 83.157                                 = 2416.66 m tan = required distance / width of river So, required distance = width of river * tan                                 = 290 m * tan 83.157                                 = 2416.66 m
