Two cars with energy-absorbing bumpers collides with car A having a speed of 8 kph to the right and B having a speed of kph to the left. Their masses are Ma = 1270 kg and Mb = 2000 kg. If the duration of the collision of the two cars is 0.1 sec., what is the average acceleration to which the occupant of car A is subjected?
