First, find the velocity of the locked cars after the collision

Given that the cars skid forward 15ft before stopping

Kinetic energy after collision is lost due to friction

=========================

During collision momentum is conserved

Initial momentum = Final momentum

**ANSWER: **

**===============================**

K'E, = W friction

KE; = Ffriction *

KE;=uN*d

Mvi = u Mg*d

bu; = 4g d

Vj = 2 * ug*d

Uf = 28.655ft/s

mcarcar + mtruck Utruck = Muf

mcarucar + mtruck Utruck = (mcar + mtruck)UF
