Since both cars move together after the collision, then this is an example of an inelastic collision. The formula for an inelastic collision is as follows:
m1u1 + m2u2 = (m1 + m2)v
Where:
m1 = mass of the first object
m2 = mass of the second object
u1 = initial velocity of the first object
u2 = initial velocity of the second object
v = final velocity
Substituting the given values to solve for v:
900*22 + 900*15 = (900 + 900)v
v = 18.5 m/s
