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 + ( ( vo sin )^2 - 4 (-h) (0.5g))] / ( 2 * 0.5 g)

motion along horizontal

D = vo cos * t

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

A spherical cannonball of mass 2M is launched with an initial velocity v0 at an angle of 45° above the horizontal. There is an explosive charge between the two halves of the cannonball which is detonated when the cannonball has reached the highest point of its trajectory. One half of the cannonball (mass M) is propelled backwards exactly along the original trajectory and lands back in the cannon (good trick!). Ignore air resistance for this problem. a) Assuming level terrain,...

An airplane flying in the air with a constant velocity of 240 m/s horizontally experiences a force due to gravity, directed downwards with a magnitude of 4×10^6 N, and a force generated by the engines, directed forwards with a magnitude of 3 × 10^6 N. a. In light of Newton’s first law, why must there be a third force acting on the airplane? Calculate the magnitude of this third force, and explain its physical origin. Draw this third force on...

An airplane weighing 5,000 lb is flying at standard sea level with a velocity of 550 mi/h. At this velocity, the L/D ratio is a maximum. The wing area and aspect ratio are 200 ft2 and 8.5, respectively. The Oswald efficiency factor is 0.93. Calculate the total drag on the airplane. Assume ?? = 0.002377 slug/ft3. (Round the final answer to one decimal place.) The total drag on the airplane is _______lb.

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?
