Asked by GET DAT
An automobile has a mass of 2150 kg and a velocity of +18 m/s. It makes a rear-end
collision with a stationary car whose mass is 1850 kg. The cars lock bumpers and skid
off together with the wheels locked. What is the velocity of the two cars just after the
collision?

momentum is conserved, so
2150*18 + 1850*0 = (2150+1850)v
solve for v
2150*18 + 1850*0 = (2150+1850)v
solve for v
