A sledthat has a mass of 8.8kg moves horizontally at 20 km/h. When it passes under a bridge 13kg of snow drops ontothe sled. What is its subsequent speed?

Isn't this in inellastic collision equation. I used (m1v1)+(m2v2)=(m1+m2)(vf)

m1=8.8kg

v1=20km/h

m2=21.8kg

v2=20km/h

I got 20km/s where did i go wrong?
