A boat traveling at 12.50 m/s relative to the water aims to go straight across a river. If the river is 109.0 m wide and the current in the river is 3.50 m/s, how far downstream will the boat land on the other side of the river? Calculate the answer in meters (m) and rounded to three significant figures.

D | Question 13 5 pts A river flows due east at 3.0 m/s. A boat crosses the 300-m-wide river by maintaining a constant velocity of 10 m/s due north-east relative to the water. If no correction is made for the current, how far does the boat move by the time it reaches the far shore? O 173 m, upstream O 346 m, downstream O 45 m, upstream O 90 m, downstream
A swimmer, capable of swimming at a speed of 1.02 m/s in still water (i.e., the swimmer can swim with a speed of 1.02 m/s relative to the water), starts to swim directly across a 2.96-km-wide river. However, the current is 0.550 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?
3) If there weren't any current in the river, the motorboat, pointing straight across the river would go from point A to point B in 30 minutes. But there is a current in the river: the water moves 8 km/hour, and the boat gets carried with it. If the motor straight across the river, it will land downstream of B, at point C. boat still points 8km/hr
A swimmer, capable of swimming at a speed of 1.60 m/s in still water (i.e., the swimmer can swim with a speed of 1.60 m/s relative to the water), starts to swim directly across a 2.67-km-wide river. However, the current is 1.40 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river? (Write on paper)
A swimmer, capable of swimming at a speed of 1.5 m/s in still water (i.e., the swimmer can swim with a speed of 1.5 m/s relative to the water), starts to swim directly across a 3.0-km-wide river. However, the current is 0.91 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? Incorrect: Your answer is incorrect. s (b) How far downstream will the swimmer be upon reaching the other side...
A river flows due east at 1. 50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.0 m/s due north relative to the water. (a) What is the velocity of the boat relative to the shore? (b) If the river is 300 m wide, how far downstream has the boat moved by the time it reaches the north shore?
A Swimmer speed in still water is 1.85m/s. If the boat is traveling north directly across a river whose westward current has a speed of 1.2m/s at what upstream angle must the boat head?
A river flows due east at 2.69 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 12.2 m/s due north relative to the water. What is (a) the magnitude (m/s) and (b) the direction (degrees east of north) of the boat’s velocity relative to shore? (c) If the river is 324 m wide, how far (m) downstream has the boat moved by the time it reaches the north shore?
