An airplane is flying 1200 m above the ground at a speed of 200 m/s. It drops a package carrying vaccines for a local community that hits the ground after
traveling a horizontal distance of 3130 m.

As the third plane comes by to make the drop, it has a catastrophic engine failure and the pilot has to eject, throwing him straight up from the plane. Assuming that he undergoes free-fall acceleration until he lands describe what would happen to how far the pilot travels(in relation to 3130 m) and briefly explain your answer.

An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).
