An airplane is flying with a velocity of v0 at an angle of α above the horizontal. When the plane is a distance h directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance. Take the free fall acceleration to be g.

Solutions

Expert Solution

using 2nd equation of motion along vertical axis

0 = h + vo sin * t - 0.5 gt^2

0.5 gt^2 - vo sin t - h = 0

solving for t

t = [vo sin + $\sqrt$ ( ( vo sin )^2 - 4 (-h) (0.5g))] / ( 2 * 0.5 g)

motion along horizontal

D = vo cos * t

D = vo cos * [ vo sin + $\sqrt$ (( vo sin ) ^2 + 2gh)] /g

An airplane is flying at a constant horizontal velocity of 184.5 m/s and drops a rocket. The rocket falls for 10.24 s without air resistance and under the influence of gravity only, and then fires its thrusters. From the moment the thrusters are one, the rocket has a net acceleration of 5.481 direscted 30.21 degrees above the horizontal. How far apart are the plane and the rocket when the rocket passes back through the cruising altitude of the plane?
