Homework Answers
1, from the third law of Newton, we can say that every action has equal & opposite reaction.
And in this scenario action is 100N applied by jane on rock, hence reaction by rock on jane will also be 100N
2. Using second law of Newton, that is net force on object will be equal to the product of mass and acceleration of the object.
Since the acceleration of the crate is zero. (Given that you are pulling with constant velocity)
Hence net force on crate is zero. Now if you are pulling with 350N then there must be friction acting in the opposite direction on the crate with equal magnitude in order to cancel out your force. Hence the magnitude of friction force on crate will be equal to 350N.

1. You want to move a 500-N crate across a level floor. To start the crate moving, you have to pull with a 230-N horizontal force. Once the crate breaks loose and starts to move, you can keep it moving at constant velocity with only 200 N. What are the coefficients of static and kinetic friction? 2. In the previous example, suppose you move the crate by pulling upward on the rope at an angle of 30.0◦ above the horizontal....
