A boat crossing a wide river moves with a speed of 18.0 km/h relative to the water. The water in the river has a steady speed of 8.00 km/h due east relative to the earth. a) If the boat heads due south, determine the speed of the boat relative to an observer standing on the shore. km/h 9. b) What is the angle made between the velocity of the boat relative to the observer and the south direction? 10. c)...

2. The water in a river moves with velocity 4ims. A boat starts at the bank and this bank, bank-A, is along the i direction. The boat's captain wants to cross the river to the opposite bank, bank-B, which runs parallel to bank-A. The captain sets the engine such that the boat would have a speed of 5ms- in still water. What is the velocity vector of the boat and the angle of the boat's travel relative to bank-A for...

A straight river flows east at 10 mph. A motorboat heads from the south shore of the river at a heading of N30ºW toward the opposite shore at a speed of 20 mph and maintains that heading. Do the following: • Draw a diagram of the situation. Show your axes. • Express the velocity of the river as a vector in component form ai+bj. • Express the velocity of the motorboat relative to the water as a vector in component...

You are planning to cross a river by a small motor boat. The speed of your boat is v = 2.71 m/s in still water. At which angle with respect to the perpendicular crossing direction do you need to aim your boat, if you want to cross the river in the shortest possible distance? The speed of the water is 1.19 m/s. 26.0 deg You are correct. Your receipt no. is 155-6363 Previous Tries After a day of very heavy...

A 0.20-km wide river has a uniform flow speed of 4.054 m/s toward the east. A boat with a speed of 80 m/s relative to the water leaves the south bank and heads in such a way that it crosses to a point directly north of its departure point. How long does it take the boat to cross the river? 29s 23s 25s 27s 17s

A boat crossing a wide river moves with a speed of 17.0 km/h relative to the water. The water in the river has a steady speed of 6.00 km/h due north relative to the earth. 1) What is the angle made between the velocity of the boat relative to the observer and the west direction? 2) At what angle against the steam must the boat be headed with respect to the west direction in order for it to proceed west...

A boat, with a maximum speed of 8.10 km/hr in still water, is attempting to cross a river. Assume that the water flow is uniform, at a rate 4.11 km/hr and that the boat's direction leads it to land directly across from its starting point. A.)How much time will the trip require if the river is 0.830 km wide, B.) Use a vector diagram to figure out the velocity perpendicular to the shore. Use Distance = speed * time to...

You are planning to cross a river by a motor boat from point A to B. Points A and B are located exactly opposite from each-other. The speed of the boat is v = 2.55 m/s in still water. The river flows with a speed of w = 1.95 m/s. At which angle θ should you aim your boat to go from A to B?

The velocity of the current in a river is C = 0.6i + 0.8j km/hr. A boat moves relative to the water with velocity v=7i km/hr. a. What is the speed of the boat relative to the riverbed? b. What angle does the velocity of the boat relative to the riverbed make with the vector v? c. What does the angle from part b tell us in practical terms?
2. The water in a river moves with velocity 4ims. A boat starts at the bank and this bank, bank-A, is along the i direction. The boat's captain wants to cross the river to the opposite bank, bank-B, which runs parallel to bank-A. The captain sets the engine such that the boat would have a speed of 5ms- in still water.
