We learned in class that the kinetic energy (KE) of an object with mass m moving at velocity v is KE =½ m v^2. Accordingly, the kinetic energy (KE) per unit mass (m) of a body moving at velocity v is KE/m=v^2 /2. What is the asteroid’s kinetic energy per unit mass (J/kg) for an impact at this velocity? State your answer in units of J/kg. velocity is 29.8 km/s

A moon of mass m orbits around a non-rotating planet of mass M with orbital angular velocity . The moon also rotates about its own axis with angular velocity .
1. A moon of mass \(m\) orbits around a non-rotating planet of mass \(M\) with orbital angular velocity \(\Omega\). The moon also rotates about its own axis with angular velocity \(\omega\). The axis of rotation of the moon is perpendicular to the plane of the orbit. Let \(I\) be the moment of inertia of the moon about its own axis. You can assume \(m<<M\)so that the center ofmass of the system is at the center of the planet.(a) What is...
