Question: A volcanic ash flow is moving across horizontal ground when it encounters a L 0 upslope. The front of the flow then travels 920 m

A volcanic ash flow is moving across horizontal ground when it encounters a L₀ upslope. The front of the flow then travels 920 m up the slope before stopping. Assume that the gases entrapped in the flow lift the flow and thus make the frictional force from the ground negligible; assume also that the mechanical energy of the front of the flow is conserved. What was the initial speed of the front of the flow?
