What will happen when a stone is thrown from a moving train?

Throwing a stone from a moving train involves the same type of calculations as throwing a stone from a stationary platform. The difference is that you now consider the added horizontal velocity imparted by the moving train. If you throw forward, the train's velocity is added to your contribution to the stone. If you throw backward, the train's velocity is subtracted from your contribution to the stone. If you throw sideways, the train's velocity does not alter your contribution to the stone. Whether any of this matters or not depends on friction due to the different air velocities encountered by the stone. Vertical velocity is relatively unchanged by the train's contribution. The stone will still go up (if you include an upward vector in your throw) and it will still go down. The end result is that the stone will hit the ground at some point. That point will be relatively the same in both cases, except for the minor difference due to air velocity.


What is the Difference between WBM and WMM roads?

WBM (Water Bound Macadam) and WMM (Wet Mix Macadam) are used for Road construction in Base course layer. WMM is a new technology. difference between WBM and WMM can be summarized as below:Stone aggregate used in WBM is larger in size compared to WMM. In case of WBM its size varies between 45 mm to 90 mm depending upon the grade while in case of WMM aggregate size varies between 4.75 mm to 20 mmIn case of WBM stone aggregate, screening material and binders are overlaid one after another respectively at the time of construction. But in case of WMM, aggregate and binding materials are premixed in a batching plant or concrete mixing machine and then brought to site for overlaying and rolling.Materials used in WBM are stone aggregate, screening material (Kankar or murrum or smaller stone aggregate for filling up the voids ) and/or binding material (stone dust or Quary dust of PI not less than 6). materials used in WMM are Stone aggregate and binders (Stone dust or Quary dust of PI not less than 6)Quantity of WBM is generally measured in Cubic Meter while quantity of WMM is measured in Square Meter.
