Two cars, one a compact with mass 1200kg and the other a large gas-guzzler with mass 3000 kg, collide head-on at typical freeway speeds. (a) Which car has a greater magnitude of momentum change? Which car has a greater velocity change? (b) if the target car changes its velocity by ?v,? alculate the change in the velocity of the small car in terms of ?v.? (c) Which car’s occupants would you expect to sustain greater injuries? Explain.

Solution 39E Step 1 of 5: The momentum of the system of the two cars is conserved. (If we neglect the external forces during collision) mass of the small car,m = S200 kg mass of the large car,m = L000 kg velocity of the small car,v S velocity of the large car,v L
