Chapter 9, Problem 68P
(II) Find the center of mass of the ammonia molecule. The chemical formula is NH3. The hydrogens are at the corners of an equilateral triangle (with sides 0.16 nm) that forms the base of a pyramid, with nitrogen at the apex (0.037 nm vertically above the plane of the triangle).

- You friend wonders how a rocket continues to climb into the sky once it is sufficiently high above the surface of Earth so that its expelled gasses no longer push on the surface. How do you respond?arrow_forwardThree skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?arrow_forwardThree steel spheres of equal mass are suspended from the ceiling bystrings of the same length that are spaced at a distanceslightly larger than the diameter of the spheres. After pulling it andReleasing it, sphere A hits sphere B, which then hits sphere C.If the coefficient of restitution between the spheres is denoted by e and by v0 thevelocity of A just before it hits B, determine, (a) the velocitiesof A and B immediately after the first collision, b) the velocities ofB and C immediately after the second crash. c) If now it is assumedthat n spheres are suspended from the ceiling and that the first is pulled and released asdescribed above, determine the velocity of the last sphere aftertakes the first hit. d.Use the result of part c to find the velocity of the last sphere.when n = 6 and e = 0.95.arrow_forward

Where should afourth object of 8.0 kg be placed so that the center of mass ofthe four-object arrangement will be at (0.0, 0.0) m?arrow_forwardTo keep the calculations fairly simple, but still reasonable, we shall model a human leg that is 92.0 cm long (measured from the hip joint) by assuming that the upper leg and the lower leg (which includes the foot) have equal lengths and that each of them is uniform. For a 70.0 kg person, the mass of the upper leg is 8.60 kg, while that of the lower leg (including the foot) is 5.25 kg.
