Question

An airplane
flies horizontally at a constant velocity vx = 115m/s and height h =
1050m. It drops a care package.
 The magnitude and direction of the velocity vector of the package when it reaches
the ground is closest in value to:
A 115m=s and 51
B 143m=s and 51
C 184m=s and 51
D 184m=s and 309

Answer 1

1st use

h=vi*t + .5at^2 to solve for t because a = -9.81m/s^2 and vi =0

then with t use

V = Vi + at to find the y component of the Packages velcoity

V = (Vx^2 + Vy^2)^(1/2)

Angle = arctan (vy/vx)

Answer 2

Thank you so much. I like your drawing too @demitris
