Problem 10: While watching the clouds pass by, you notice a European swallow flying horizontally at a height h = 21.9 m above you. When the swallow is directly overhead, it drops an m = 10.7 kg coconut. From your ornithological studies, you know that the air-speed of this particular species of swallow while carrying such a load is vo = 7.73 m/s. In this problem you may neglect air friction. Refer to the diagram. Assume the origin of the coordinate system there is at your head.

While watching the clouds pass by, you notice a European swallow flying horizontally at a height h = 21.1 m above you. When the swallow is directly overhead, it drops an m = 10.2 kg coconut. From your ornithological studies, you know that the air-speed of this particular species of swallow while carrying such a load is v0 = 7.97 m/s. In this problem you may neglect air friction. Refer to the diagram. Assume the origin of the coordinate system there is at your head. Calculate the magnitude of the angular momentum L, in kg ⋅ m2/s, of the coconut as observed by you at the moment it is released directly overhead. Calculate the magnitude of the angular momentum L, in kg ⋅ m2/s, of the coconut as observed by you one second after it is released directly overhead (t = 1 s). Calculate the magnitude of the angular momentum L, in kg ⋅ m2/s,of the coconut as observed by you immediately before it hits the ground.
Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. It is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. A bird with these tendencies is released from an island that is 4 km from the nearest point B on the shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Assume that the bird instinctively chooses a path that will minimize its energy expenditure. Points B andD are 9 km apart. (Round your answers to two decimal places.) island D. nest (a) In general, if it takes 1.2 times as much energy to fly over water as land, to what point C should the bird fly in order to minimize the total energy expended in returning to its nesting area? 6.1 x km from 8 (b) Let W and L denote the energy (in joules) per kilometer flown over water and land, respectively.

Q: A truck (m = 10000 kg) is traveling at a speed of 30 m/s (about 70 mph) down the Kailua side of the Pali Highway when its brakes cut out. The truck driver quickly navigates to a "runaway truck ramp" to slow down enough that he can apply his emergency brakes. If the truck was originally at a height of 10.0m above the bottom of the "runaway truck ramp", and friction is negligible, how high up the ramp (height) does the truck need to go to come to a stop?

A 235 kg roller coaster is at the top of a hill with a velocity of 5.60 m/s from a height of 100.0 m above the ground. A) Determine the velocity of the roller coaster at a height of 40.0 m furtherdown the track, neglecting friction. B) What reference point did you choose as zero height? Show how you could come up with the same answer to A if you chose another reference point for height.
