Physics 7B Exit Handout DLM 11 FNTs 7.1-7 . Two asteroids collide head-on and stick together. Before the collision, asteroid A (mass 1,000 kg) moved at 100 m/s, and asteroid B (mass 2,000 kg) moved at 80 m/s in the opposite direction. Use momentum conservation (make a complete Momentum Chart) to find the velocity of the asteroids after the collision. 7.2-7 . Two asteroids identical to those in FNT 1 collide at right angles and stick together; i.e, their initial velocities were perpendicular to each other (take A initially moving to the right and B initially moving up). Use momentum conservation (make a complete Momentum Chart) to find the velocity (magnitude and direction with-respect-to the velocity asteroid A had before the collision) of the asteroids after the collision. 7.2-8 Determine the fractional decrease in total kinetic energy of the two asteroids in the previous two FNTs when they collide. If the average specific heat of the material composing the asteroids is assumed to be that of ice (2.05 kJ/kg·
