Question
Two cars, travelling in the same direction . first car mass 1400 kg
skids straight into the back of second car mass 1000 kg.
Before the impact, car B is moving at a speed of 8 m s-1
. The two cars become entangled
after the impact and continue to move in the same straight line with a speed of 15 m s-1
.
After the collision, the cars skid along the road and come to rest at a distance of
20 meters. Calculate:
i. the velocity of the car A before the impact, and
ii. the acceleration of entangled cars as they come to rest
