Question

# A loaded lorry of mass $$12000\ kg$$ moves with a velocity of $$12\ m/s$$. Its velocity becomes $$10\ m/s$$ after $$5\ s$$What is the initial momentum and what is the final momentum?

Solution

## initial momentum $$=mu$$$$=12000 \times 12=144000\ kg\ m/s$$ Final momentum $$=mv$$$$=12000 \times 10=120000\ kg\ m/s$$Physics
