A boy plans to cross a river in a rubber raft. The current flows from north to south at 1 m/s. In what direction should he head to get across the river to the east bank in the least amount of time if he is able to paddle the raft at 1.5 m/s in still water? (a) directly to the east (b) south of east (c) north of east (d) The three directions require the same time to cross the river.

A ferryboat has a still water speed of 10.3 km/hr. Its helmsman steers the boat due north across a river that runs with a current of 5.2 km/hr east. If the trip lasts 1.5 hr, how wide is the river? How far east does the ferry travel during the trip?
If a swimmer swims straight line with 2m/s velocity and the current of river pushes the swimmer perpendicularly to the right at 1m/s velocity, what would be the resultant velocity of the swimmer?
A jetliner with an airspeed of 1000 km/hr sets out on a 1500 km flight due south. To maintain a southward direction, however, the plane must be pointed fifteen degrees west of south. If the flight takes 100 min, what is the wind velocity?

A cannon ball is fired with an initial speed of 123 m/s at angle of 60 degrees from the horizontal. Express the initial velocity as a linear combination of its unit vector components. ( m/s) + ( m/s) At the maximum height, the speed of the cannon ball is v = m/s and the magnitude of its acceleration is a = m/s2. The time needed to reach maximum height is t = s. The maximum height reached by the cannon ball is H = m.
A man can row at 8.5 mi/hr in still water. If velocity of stream is 1.5 mi/hr, at what angle with the river bank must the boat be steered to travel the shortest distance in crossing river? What is the velocity of the boat with respect to the river bank in mi/hr?

How far north or south of their original position are the birds?
