A bottle dropped from a balloon reaches the ground in 50.0 s. What was the height, in meters, of the balloon above the ground, if it was ascending with a speed of 20.0 m/s when the bottle was dropped? [Neglect air resistance. Assume g = 9.80 m/s2] [Answer with 4 significant figures]
A gnat takes off from one end of a pencil and flies around erratically for 17 s, seats on a wall for 4.6 s, and continues flying for the next 0.8 seconds before landing on the other end of the same pencil. If the gnat flew a total distance of 2.5 m, and the pencil is 9 cm long, find the gnat's average speed. Answer:____ Units:_____ .
After they are released, the large mass, m2, falls a distance h and hits the floor, while the small mass, m1, rises the same distance h. (a) Find the speed of the masses just before m2 lands. Assume the ropes and pulley have negligible mass and that friction can be ignored. (Use any variable or symbol stated above along with the following as necessary: g for the acceleration due to gravity. Do not substitute numerical values; use variables only.) v = (b) Evaluate (in m/s) your answer to part (a) for the case where h = 1.5 m, m1 = 3.2 kg, and m2 = 4.3 kg.
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.
