You were in a tug-of-war contest which your team won. Write a letter to your friend that tells why your team won the contest. Remember to include unbalanced forces, potential energy, kinetic energy and net force. ***Your goal is to write an entire page/letter to a friend using the vocabulary provided and the knowledge you have about Force & Motion. *

How i would start it:

(i dont know any of the vocab. of Force & Motion)

Dear (name of friend),

Our team won because of strength as well as team work. Even though you're my friend, I would not go easy on you. It's a contest and when it starts I will act like I don't know you. Good job to your team!

This is only an idea you can change it a bit and the vocab.

Hope it helped :)

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

prolly a beacuse the momentuem the car has increases while going down hill
