a pilot has his small airplane heading due north at 50 km/h. after two hours of flight he finds himself 40 km east and 70 km north of his starting point. find the velocity of the crosswind that is driving the plane off-course?

Solutions

Expert Solution

Given:

Time of flight,

Speed of plane,

North means y-direction

----------

Let be the speed of the wind

And let be the resultant velocity

An airplane pilot wishes to fly to his destination 500 mi due west, but the wind is blowing at 23.1 mi/hr toward 14.1° north of west. The speed of the plane relative to the air is 166.5 mi/hr. At what angle (south of west) must the pilot orient the plane in order to fly to his destination directly? If the pilot orients the plane at that angle, what will be the speed of the plane relative to the ground?

James has just jumped out of an airplane. After he opens his parachute he experiences 2 forces: the constant force of gravity, and a wind drag that is proportional to his velocity. His height may therefore follow the equation: d2h/dt2 = -9.8 - 2(dh/dt). As a second-order differential equation, this is not technically solvable by separation of variables. However, because the variable h appears only in its derivatives, we can turn this into a first-order equation, and solve that by...
