The captain of a plane wishes to proceed due west. thecruising speed of the plane is 245 m/s relative to the air. aweather report indicates that a 38.0-m/s wind is blowing from thesouth to the north. in what direction, measured with respectto due west, should the pilot head the plane relative to theair?

South-West direction

Explanation:

Let  be velocity of the plane relative to the air,  be velocity of the air relative to the ground,  is the velocity of the plane relative to the ground

therefore,

From the triangle attached, the angle characteristics to the direction of relative velocity of the plane can be found

 South-West direction

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

i think if it were me i whould divide 300 dide 15
