A squirrel is running westward along the shore at 2.0km/h. The water flows to the east at 7.0km/h relative to the shore. A boat is also traveling to the east at 30km/h relative to the water. If an airplane is traveling east at 150km/h relative to the squirrel, then what is the velocity of the boat to the airplane? Set the eastward direction as positive.
Homework Answers
The speed of the boat relative to shore is 30 + 7 = 37 km/h to the east
The speed of the boat relative to the squirrel is 37+2 = 39 km/h to the east
The velocity of the boat relative to the airplane is 39-150 = -111 km/h to the east
or 111 km/h to the west

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...

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 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?

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 straight river flows east at a speed of 8 mi/h. A boater starts at the south shore of the river and heads in a direction 60° from the shore (see the figure). The motorboat has a speed of 20 mi/h relative to the water. (Assume that the i vector points east, and the j vector points north.) 60° (a) Express the velocity of the river as a vector in component form. (b) Express the velocity of the motorboat relative...
