    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

    Reminder: No collision is truly elastic! assume cart 1 has mass 234 g and initial velocity +v10 = 7.6 m/s, and cart 2 has mass 897 g. Assume the track is frictionless, and after the "elastic" collision cart 1 is moving at v1 = -4.362 m/s and cart 2 is moving at v2 = 3.035 m/s. What percentage of the original linear momentum was "lost" due to external forces? (Remember: linear momentum is a vector!) i am not asking for...

    a In mechanics, the energy of a moving body is called kinetic energy. If an object of mass (kilograms) is moving with a velocity v (meters per second), then the kinetic energy k( joules) is given by the equation ke we model the mass and inputs to a system (moving body) and the energy as output, then obnerve the system for while and deduce the following two rules of inference based on our observations Rule 1: IF x is small...
