/1 In the figure, two long barges are moving in the same direction in still water, one with a speed of 11 km/h and the other with a speed of 21 km/h. While they are passing each other, coal is shoveled from the slower to the faster one at a rate of 780 kg/min. How much additional force must be provided by the driving engines of (a) the faster barge and (b) the slower barge if neither is to change speed? Assume that the shoveling is always perfectly sideways and that the frictional forces between the barges and the water do not depend on the mass of the barges.

Question

-/1
In the figure, two long barges are moving in the same direction in still water, one with a speed of 11 km/h and the other with a speed of
21 km/h. While they are passing each other, coal is shoveled from the slower to the faster one at a rate of 780 kg/min. How much
additional force must be provided by the driving engines of (a) the faster barge and (b) the slower barge if neither is to change speed?
Assume that the shoveling is always perfectly sideways and that the frictional forces between the barges and the water do not depend
on the mass of the barges.

The trick to skipping a rock is throwing it at a low angle. This is because the surface tension of the water can only provide so much force, beyond which the rock goes into the water instead of bouncing off its surface. You throw a rock of mass m = 0.05 kg with a speed of vo = 20 m/s. The surface tension of the water can provide a maximum force of F = 5 N. The collision of the rock with the water lasts At = 0.1s. Assume it bounces off the water at the same angle and speed it collided with. Find the maximum angle (measured from horizontal) at which you can throw the rock and still have it skip off the surface. You can ignore gravity. Answer in degrees Vo = 20 0 m S V = 20 To m S
