An airplane ...

Question

An airplane flying horizontally at a constant speed of 350 km/h over level ground releases a bundle of food supplies. Ignore the effect of the air on the bundle.What are the bundle’s initial (a) vertical and (b) horizontal components of velocity? (c) What is its horizontal component of velocity just before hitting the ground? (d) If the airplane’s speed were, instead, 450 km/h, would the time of fall be longer,shorter,or the same?

Solution

a) voy = 0 km/h,
b) vox = 350 km/h,
(c) There is no significant horizontal acceleration so vx = 350 km/h,
(d) Same. Time of fall is determined by vertical acceleration and vertical initial velocity
