1 Bucket
@FoFa: So let's do the math on that: Little Johnny has a bucket (Liebherr ) that has a capacity of 6.2 cubic meters.  How many liters of water will Johnny need to fill it to capacity?  How much does water weigh per liter?  How many pounds of water were dropped on the car?6,200 liters x 2.204 lb per liter = 13,664.8 poundsOf course, we're still missing things like displacement of energy across the mass of the surface of the vehicle along with variable acceleration of the water depending upon how high it was dropped from.  We'll let
@RetiredEngineer solve those for extra-credit. Â 4951
