(a) A physicist runs straight south at velocity 8 mi/hr. She decides to change her course so that thewind is at her back (directly from the north, relative to the earth) at velocity 20 mi/hr. She decidesto change her course so that the wind will striker her right side (i.e., at 90° relative to her motion).By what angle must she change her direction of motion?

You are riding in a boat whose speed relativeto the water is 6.1m/s. The boat points at anangle of 25 degrees upstream on a river flowing at 1.4m/s. Suppose the speed of the boat relative to the water remains the same, but the direction in which it points is changed. What angle is required for the boat to go straight across the river?

What are the (d) magnitude and (e) angle of its velocity 5.0 s after launch, and (f) is the angle above or below the horizontal?
A 1.00 km wide river is flowing uniformly due South at 5.00 km/h. You want to drive your boat from the west shore (A) to a point on the other shore due East from your initial point (B). Your boat's speed relative to the water is 10.0 km/h. a.)

How long will it take to cross the river that way?
A light plane attains an airspeed of 490 km/h. The pilot sets out for a destination 790 km due north but discovers that the plane must be headed 19.0° east of due north to fly there directly. The plane arrives in 2.00 h. What were the (a) magnitude and (b) direction of the wind velocity? Give the direction as an angle relative to due west, where north of west is a positive angle, and south of west is a negative angle. (a) Number i (b) Number Units Units
