Answer to: An asteroid with a diameter of 10 km and a mass of 2. The impact force is 250 N, and the contact time is 0. When a plane dives, potential energy is converted to kinetic energy; it picks up speed as it loses altitude. 2 km/s, delivering 19 GJ of kinetic energy (KE) to the comet. DART is the first space mission designed for asteroid deflection duties. Compare the player’s momentum with the momentum of a hard-thrown 0. Without the cavity, the necessary energy was about 650 joules per gram. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Rating capacity and C-rate. Heat, or thermal energy, is a form of kinetic energy — the energy of the motion of molecules. Source: Wikipedia.
