Un’automobile di massa 800 kg e velocità 54 km/h si muove lungo una traiettoria rettilinea. Una seconda au-
tomobile di massa 900 kg e velocità 72 km/h si muove
lungo una traiettoria rettilinea perpendicolare a quella
precedente.
All'istante t = 0 s, le auto si urtano nell'origine di un si-
stema di riferimento cartesiano ortogonale e poi proce-
dono unite.
Qual è la quantità di moto totale del sistema prima
dell'urto?
Qual è il modulo della velocità finale delle due auto?
