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 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?
An athlete crosses a 24.2 m wide river by swimming perpendicular to the water current at a speed of 0.4 m/s relative to the water. He reaches the opposite side at a distance of 45.3 m downstream from his starting point. How fast is the water in the river flowing with respect to the ground?
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
(2) A boat with a maximum speed with a width d. The river is flowing with speed V. (a) Traveling in a straight line (i.e perpendicular to the shore) how long does it take the boat to et to a point directly across? (b) What is the fastest possible crossing time to any point on the opposite shore? [20 pts] v (relative to the water) is on one shore of a river
An athlete crosses a 21 m wide river by swimming perpendicular to the water current at a speed of 0.35 m/s relative to the water. He reaches the opposite side at a distance 38 m downstream from his starting point. a) How fast is the water in the river flowing with respect to the ground in m/s? b) What is the speed of the swimmer with respect to a friend at rest on the ground in m/s?
Problem 4.20 needs to row her boat across a 120 m-wide river that is flowing Mary to the east at a speed of 1 4 m/s Mary can row with a speed of 21 m/s Part A If Mary points her boat due north, how far from her intended landing- spot will she be when she reaches the opposite shore? Express your answer in meters. WA 8 : meters downstream Submit RequestAnswer Part B What is her speed with respect...
A certain river is 0.5 mi wide, and flows due east at 2.7 mi/h relative to the shore. A boat attempts to cross the river straight from one shore to the other. If the boat travels due north at 1.7 mi/h relative to the river, (a) what is the speed of the boat relative to the shore? (b) how far downstream is the boat when it reaches the opposite shore?
Problem 4.20 Mary needs to row her boat across a 200 m-wide river that is flowing to the east at a speed of 1.4 m/s. Mary can row with a speed of 4.0 m/s.
