Hello!

abhisar · Answer

Are you familiar with equations of motion?

anonymous · Answer

Yeah. I just need someone to make sure I did it right. So it would be 4.0=(x-0)/7

anonymous · Answer

4*7=28 then you add in the 10 which gives you 38.

anonymous · Answer

Would that be right?

Obviously there are units and such.
