As two boats approach the marina, the velocity of boat 1 relative to boat 2 is 2.10 m/s in a direction 47.0 ∘ east of north.If boat 1 has a velocity that is 0.800 m/s due north, what is the velocity (magnitude and direction) of boat 2?

Two boats are heading away from shore. Boat 1 heads due north at a speed of 2.97 m/s relative to the shore. Relative to Boat 1, Boat 2 is moving 28.3° north of east at a speed of 1.66 m/s. A passenger on Boat 2 walks due east across the deck at a speed of 1.18 m/s relative to Boat 2. What is the speed of the passenger relative to the shore?
Two boats are heading away from shore. Boat 1 heads due north at a speed of 3.20 m/s relative to the shore. Relative to Boat 1, Boat 2 is moving 31.3° north of east at a speed of 1.61 m/s. A passenger on Boat 2 walks due east across the deck at a speed of 1.12 m/s relative to Boat 2. What is the speed of the passenger relative to the shore?
Two boats are heading away from shore. Boat 1 heads due north at a speed of 4 m/s relative to the shore. Relative to boat 1, boat 2 is moving 30° north of east at a speed of 1.2 m/s. A passenger on boat 2 walks due east across the deck at a speed of 1.1 m/s relative to boat 2. What is the speed of the passenger relative to the shore?
3.(25 pts) Three boats are moving on a lake. The first boat (m 2570 kg) is moving at 12.5 m/s at 35.00 south of west. The second boat (m- 1560 kg) is moving at 9.65 m/s at 12.30 west of north. The third boat has a mass of 3350 kg. The boats collide, stick together, and move with a velocity of 4.55 m/s due west. Find the magnitude and direction (from the north) of the velocity of third boat.
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?
For a boat moving due north at a constant velocity of 8 m/s, what are the components of the boats velocity vector? (Assume north is +y and east is + x)?
A 280-m-wide river flows due east at a uniform speed of 4.4m/s. A boat with a speed of 6.9m/s relative to the water leaves the south bank pointed in a direction 33owest of north. What is the (a) magnitude and (b)direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west. (c) How long does it take for the...
A 200-m-wide river flows due east at a uniform speed of 3.4m/s. A boat with a speed of 8.4m/s relative to the water leaves the south bank pointed in a direction 34o west of north. What is the (a) magnitude and (b) direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west. (c) How long does it take...
A 250-m-wide river flows due east at a uniform speed of 4.0m/s. A boat with a speed of 6.9m/s relative to the water leaves the south bank pointed in a direction 26o west of north. What is the (a) magnitude and (b) direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west. (c) How long does it take...
A 250-m-wide river flows due east at a uniform speed of 2.8m/s. A boat with a speed of 7.7m/s relative to the water leaves the south bank pointed in a direction 31o west of north. What is the (a) magnitude and (b) direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west.
