The momentum of an object is the product between the mass m of the object and its velocity:

p=mv

The truck in our problem has momentum equal to

p=40120 kg m/s

and a mass of

m=1180 kg

so, if we re-arrange the previous formula, we can use these data to find the velocity of the truck:

v= (p)/(m)= (40120 kg m/s)/(1180 kg)=34 m/s
