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?
A 70 m wide river flows from north to south at a speed of 3.2 m/s. A swimmer swims relative to the water at a rate of 4.6 m/s aiming across the river at an angle of 24 degrees north of east. What is the speed of the swimmer with respect to the shore? How far downstream (south), from a point directly across the river, does the swimmer hit the shore?
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 230-m-wide river flows due east at a uniform speed of 2.1 m/s. A boat with speed of 7.8 m/s relative to the water leaves the south bank of the river pointed in a direction 35 degrees west of north. What is the magnitude of the boat's velocity relative to the ground (in m/s)? Enter only the numerical part of the answer in the box Question 2 1 pts A 212-m-wide river flows due east at a uniform speed of...
3. A boat travels at 3.5 m/s with respect to the water in a river, while the velocity of the river itself is 1.2 m/s. The boat starts at a point on one shore and travels to a point directly across on the opposite shore. If the river is 62 m wide, how long does it take the boat to cross?
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 boat moving 5.1 m/s with respect to the water crosses a river moving at 4.7 m/s with respect to the shore. The river is 71 m wide. Determine (a) the resultant velocity, (b) time to cross the river and (c) distance downstream.
A boat can travel 2.30 m/s in still water. If the boat point its prow directly across a stream whose current is 1.50 m/s. What is the magnitude of the velocity of the boat relative to the shore? v_y = m/s What is the angle of the velocity of the boat relative to the share? theta = What will be the position of the boat, relative to its point of origin, after 7.00 s? Assume that the positive x and...
A boat can travel at a speed of 4 m/s in still water. A river that is 170 m wide has a current that flows 0.85 m/s due West. a) If the boat points its bow directly across the river, how fast does the boat travel relative to the shore? m/s b) How long will it take to cross the river? s c) How far downriver will it land (the distance on the bank from the point directly across from...
A river flows due south with a speed of 2.30 m/s . A man steers a motorboat across the river; his velocity relative to the water is 4.10 m/s . The river is 850 m wide. Part A In which direction should the motorboat head in order to reach a point on the opposite bank directly east from the starting point? (The boat's speed relative to the water remains 4.10 m/s .) Part B What is the velocity of the...
