Chapter 2.1, Problem 2cT
Compare the free-body diagram for the lower book to the free-body diagram for the same book in part A (i.e., before the upper book was added).
Which of the forces changed when the upper book was added and which remained the same?
As discussed earlier, we think of each force acting on an object as being exerted by another object. The first object a force of equal magnitude and opposite direction on the second object. The two forces together are called an action-reaction or

There is a girl in a ship. The total mass of
both is 150kg. She hooks a big fish who's mass
is 250kg. The fish pulls the boat in the
opposite direction of shore (which is in right
direction) at a CONSTANT rate of one m/s.
A) there is a wind force of 500 newtons
towards shore which is the left direction, and
the force of water on the ship is 2000 newtons
upwards. What is the force of the big fish?
Draw force diagram, third law pair and show
calculations. Explain your work.
B) now, there is no wind, nor wind force. But
everything else is the same. What is the
acceleration of the ship? Draw force diagram,
third law pair and show calculations. Explain
your work.
Two blocks, A and B, were moving together at 2m/s velocity towards the right on the horizontal surface. B was pulled by the 100 N force. Suddenly, the 100 N force was removed. Assume the interfaces between A and B, between B and the floor are both frictional. From this point on, which of the figures below shows a correct free-body diagram of the horizontal forces acting on the lower block B?

In each of the scenarios, A, B, and C: Draw a free body diagram showing all forces on the mass. Make sure to indicate which force is bigger by drawing a vector of larger length.

Narrow_forwardWhich of the statements below does not coincide with the definition of Newton's 3rd Law of Motion? * O Its impossible to exert force without experiencing one. O Action-reaction pairs exist every time forces interact with matter. Forces interacting between two objects are equal in magnitude and opposite direction. O An object at rest may or may not experience action-reaction force pairs.arrow_forwardTo be clear: You must write the words "Newton's Second Law" and point to an example of it within your solution! Write out the second law using symbols, not numbers. Writing "net force = m a" does not qualify because that could be written for any object. The symbols and subscripts should clearly refer to specific forces in each diagram. Examples, good and bad, of what might qualify are shown below. The following are three examples of Newton's second law written for an object called "E" (which is not in this question). Credit would be given for the first example but not for the second or third. This is a good example: mE g−TEJ sinθ1+NER cosθ2=mE a This is a bad example that is not specific enough: Σ FE=mE a This is a bad example with unspecified numbers and without symbols: (1.7 kg) g−(3.8 N) sin(59∘)+(4.9 N)cos(34∘)=(1.7 kg) a Once you have begun your solution with symbols in Newton's Second Law, you may begin to substitute numbers as needed.arrow_forward
