Help will be rewarded.
A red wagon (mass=235) at a constant speed of 9.5 m/s. If 6.4 kg were added to the wagon, how fast would it be going now?

Answer 1

hint: conservation of linear momentum

Answer 2

Yes, I am aware of it, but I'm having trouble applying it to this particular problem.

Answer 3

\[m _{1}v _{1}=m _{2}v _{2}\]

Answer 4

Does the above equation look familiar to you? Would you expect the velocity to increase or decrease after adding mass?

Answer 5

Ah, how could I have been so silly? Thank you both for your help. XD

Answer 6

you are welcome
