More Newtons Third Law stuff

Today in class we went over part c of the Newtons Third Law example we began the other day. Afterwards we did similar questions on page 149, 1-3a in the text book.  Once we were done, we began another assignment due tomorrow, or I guess this present class.  We also got our quizzes back.


part c) find the force exerted by toboggan one on toboggan two,

Fnet=ma
       =(55 kg)(2.2 m/s squared [E])
       =121 N [E]

We take the force of 22 N [W] from b and plug  it into another equation to find the total force.

Fnet= Fa + Fa
 121= -22 + Fa
   Fa= 143 N [E]


Next is Kurtis
