Question

9. a) An airplane flies 4032km with a constant speed of 1008km/h and another 1480km with a constant speed of 888km/h. How much in total does it take to travel these distances? *

Answer 1

Answer:

From the given data,

a) v

oy

=0 km/h,

b) v

ox

=350 km/h,

(c) What is its horizontal component of velocity just before hitting the ground? There is no significant horizontal acceleration so v

x

=350km/h,

(d) If the airplane's speed were, instead, 450 km/h, would the time of fall be longer, shorter, or the same? Same. Time of fall is determined by vertical acceleration and vertical initial velocity
