Post by: mikael on May 14, 2014

 
A car of mass  1028 kg collides head-on with a parked truck of mass 2000 kg. Spring mounted bumpers ensure that the collision is essentially elastic. If the velocity of the truck is 17 km/h (in the same direction as the car's initial velocity) after the collision, what is the initial speed of the car? 
A)
 
25 km/h 
B)
 
50 km/h 
C)
 
38 km/h 
D)
 
13 km/h
