1. The problem statement, all variables and given/known data Car A (m1=1405kg) crashes into Car B (m2=873kg) which is stationary and perpendicular to Car A. Car B is moved a distance of 1.8m out of the way and Car A rolls to a stop 9.6m away at 1.93 m/s. Assuming the coefficient of friction is 0.8, can the velocity of Car A be calculated before impact? Please see amazing diagram attached for a clear depiction of crash. Variables: m1=1405kg m2=873kg v1=? v2=0m/s µ=0.8 d=1.8m 2. Relevant equations W=F*d F=µmg 3. The attempt at a solution Force required to move Car B F=µmg = 0.8*873*9.8 = 6844N Work done to move Car B W=F*d = 6844 * 1.8 = 12,320J Not sure where to go from here...can anyone please point me in the right direction?
