Then the car's initial velocity is -50 mph. The collision is totally inelastic, so the final velocity of both fly and car is -44 mph. Total initial momentum = (4/1000)u - 1980*50 = 0.004u - 99000 kg mph. Total final momentum = (1980 + 4/1000)*(-44) =
Physical properties: Properties that describe the look or feel of a substance. Examples: * Color * Hardness - lead is soft * Density * Texture * Shape * Size * Phase (solid, liquid, gas) Choose 5 of those and look at a pencil. Chemical properties:
If the charged ball is suspended be the string which is deflected by the angle á, the forces acting on it are: mg (downwards), tension T (along the string - to the pivot point), and F (electric force –along the line connecting the charges). Projections
