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.

Question

a)What is the bundle’s initial vertical component of velocity? =0

b)What is the bundle’s initial horizontal component of velocity? =350

c) What is its horizontal component of velocity just before hitting the ground? =350

I got the answers, but how do I calculate them?

Thank you!!

Answer 1

Vo = (350km/h,0deg.).

a. Yo = ver. = 350sin(0) = 0.

b. Xo = hor. = 350cos(0) = 350km/h.

c. Xo = hor. = 350cos(0) = 350km/h.
