Asked by willy n

a 20.0 kg child on an 80 kg boat throws a 5 kg package horizontally with a speed of 10 m/s. Calculate the resulting density of the boat, assuming it was initially set at rest.
Answered by bobpursley
Density? What was the original volume? Assuming the density of the boat to be originally about .50, then

volume= 105kg/.5=210liters

Then new density is 100kg/210liters=.476
