Modeled after the triatomic molecule problem that is let's consider the three atoms composing the molecule have different masses and coordinate, while the axis of rotation is still y-axis. The first atom has a mass of 7.281 kg, with x coordinate at 6.769 m and y coordinate at 9.989 m. The second atom has a mass of 61.310 kg, with x coordinate at 39.549 m and y coordinate at 25.180 m. The third atom has a mass of 49.316 kg, with x coordinate at 35.553 m and y coordinate at 31.216 m. What is the moment of inertia in the unit of kg m2 with respect to the y axis?

In the figure, two satellites, A and B, both of mass m = 49.1 kg, move in the same circular orbit of radius r = 7410 km around Earth (mass ME = 5.98×1024 kg) but in opposite senses of rotation and therefore on a collision course. (a) Find the total mechanical energy EA+ EB of the two satellites + Earth system before the collision. (b) If the collision is completely inelastic so that the wreckage remains as one piece of tangled material (mass = 2m), find the total mechanical energy immediately after the collision. (c) Just after the collision, is the wreckage falling directly toward Earth’s center or orbiting around Earth?
A package of mass 7 kg sits at the equator of an airless asteroid of mass 4.0 1020 kg and radius 5.9 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 188 m/s. We have a large and powerful spring whose stiffness is 2.1 105 N/m. How much must we compress the spring?

A can full of soda (total mass is about 375 g, where 355 g comes from the liquid and 20 g from the aluminum can, radius is about 33 mm) is released on a slope. The slope has an angle of 30° of inclination and a length of 40 cm. Due to friction, the can roll over the slope without slipping. Determine the time it takes for the can to reach the bottom of the slope.Repeat the calculation for the empty can (m = 20 g and R = 33 mm). Note: In both cases, ignore the contribution from the top and bottom metallicparts of the can (disks) to the moment of inertia.
An object with mass M slides across a frictionless half-circular slide of radius R. The object is initially held stationary at the top of the slide. The initial height is, hi = R. The mass is released and slides down, around the bottom, and back up the other side. The radius of the slide is R = 5.79 m and the mass of the object is M = 37 kg. When the object is moving up the slide, at an angle θ = 18o from the vertical, what is the normal force on the object?
An asteroid has a mass of m = 2.6 x 106 kg and is approaching Earth. When the asteroid is exactly 3 radii away from the Earth's centre, it's speed relative to the Earth's centre is u = 8.7 x 103 ms-1. The asteroid then falls to the Earth's surface, but remains intact without dissipating any energy as it passes through the Earth's atmosphere. If the rotation of the asteroid and the Earth is ignored, what is the kinetic energy of the asteroid just before it hits the ground? The Earth has mass ME = 5.98 x 1024 kg and a radius of 6.38 x 106 m. To find the relevant potential energies, you must use G = 6.67 x 10-11 N m2 kg-2
