You've seen this bfore!


If L/V=t, then after what time does the wedge start toppling off the edge of the cliff??

The hoz. plane is smooth.

    ya..correct ans. is 5t/3.

    i wanted to remind you of the relation of center of mass with toppling..
    the wedge starts toppling when its COM comes vertically abv. the cliff. that occurs at V/(5L/3)..
    as the initial distance of COM from the cliff is 5L/3.

    plz. see that the COM of a triangular object is at the centroid..
