A 5-kg fish swimming at a velocity of 1 m/s swallows an absent-minded 1-kg fish swimming towards it 4 m/s. Wha tis the speed of the larger fish after lunch?
Risposta:
Ho trovato #0.17m/s#
Spiegazione:
Possiamo usare conservation of momentum Il #x# direction:
Così:
#(5*1)+(1*-4)=(5+1)v#
#5-4=6v#
#v=1/6=0.17m/s#
