Answer:
vcm = 75.1052631579 km/ h
Explanation:
Center of mass is the point where the mass of a system is equally distributed .
m1 = mass of the Chrysler
v1 = velocity of the Chrysler
m2 = mass of the Ford
v2 = velocity of the Ford
vcm = velocity center mass
vcm = (m1 × v1 + m2 × v2) / m1 + m2
m1 = 2500 kg
m2 = 1300 kg
v1 = 84 km/h
v2 = 58 km/h
vcm = (2500 × 84 + 1300 × 58)/ 2500 + 1300
vcm = (210000 + 75400)/
3800
vcm = 285400
/3800
vcm = 75.1052631579 km/ h
