2) As shown below, a passenger pulls on the suitcase that has a mass M, with a force of
30.0 N and displaces the suitcase horizontally 10.0 m. The angle between F and the
horizontal is 30°. The coefficient of kinetic friction HK = 0.45
Force and displacement
are not in the same direction;
here W = FAx.
Ar
(b)
The force that the passenger applies to the suitcase is not in the same direction as the
displacement of the suitcase, so we have to find the "piece" or "component" of the force
vector F that is in the same direction as the displacement. In other words, we must find
F, = Fcos0, where 0 is the angle between the two vectors, F and Fx
a. If 0 = 30°, what work is done on the suitcase by the passenger?
b. What is the work done on the suitcase by friction? (remember that we can always
express the force due to kinetic friction as follows: f = HgN; so now that we have
the force we can find the work done by multiplying this force by the displacement. Be
careful --- the normal force is NOT…

wall by someone pushing on it with a force directed upward
at 28° above the horizontal. The coefficients of static and
kinetic friction between the box and wall are 0.40 and
0.30, respectively. The box slides down unless the applied
force has magnitude 23 N. What is the mass of the box?
49. (II) Two crates, of mass 65 kg and 125 kg, are in contact and

friction is 0.18, calculate (a) the acceleration of the sys-
tem, and (b) the force that each crate exerts on the other.

- A crate of weight Fg is pushed by a force P on a horizontal floor as shown in Figure P4.83. The coefficient of static friction is s, and P is directed at angle below the horizontal. (a) Show that the minimum value of P that will move the crate is given by P=sFgsec1stan (b) Find the condition on in terms of , for which motion of the crate is impossible for any value of P.

Taking the coefficient of kinetic friction as 0.200, find the tension in the string.arrow_forwardA car is stuck in the mud. A tow truck pulls on the car with the arrangement shown in Fig. P4.32. The tow cable is under a tension of 2 500 N and pulls downward and to the left on the pin at its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut; that is, each is a bar whose weight is small compared to the forces it exerts and which exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tension or compression in each strut. Proceed as follows. Make a guess as to which way (pushing or pulling) each force acts on the top pin. Draw a free-body diagram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations. From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means that the direction should be reversed, but the absolute value correctly gives the magnitude of the force. If a strut pulls on a pin, it is in tension. If it pushes, the strut is in compression. Identify whether each strut is in tension or in compression.arrow_forward

If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmons acceleration and (b) the magnitude of the force F during this interval.arrow_forwarda) Three forces F1, F2 and F; keep a point mass M in equilibrium.
