Question

Example: book at rest on table with rope pulling to the right and Chr following numbers: the weight is 10 N, the tension is 15 N, and Chris pushes with 1 FBD B: is pushing to the left. Use the N2 equations: BT BC BR s BT BE Find the static friction: Find the normal force: More questions: Which force completes the Newton's third law force pair with the normal force exerted on the bool the table? Which force completes the Newton's third law force pair with the weight of the book? R > Fec > f Is the following ranking correct?

Explanation / Answer

static friction = tension in rope - force by chris = 15 - 10 = 5 N

Normal force = Weight of book = 10 N

Weight of book

Normal force by table on book

Correct as the given order is 15>10>5
