You can hold a book against the wall, preventing it from sliding down, if you press your hand against it. Suppose the coefficient of static friction between the book and the wall is 0.450, but there is no friction between your hand and the book. The mass of your book is 3.75 kg. What minimum force (P) do you need to apply to keep the book from slipping down the wall? Give your answer in units of Newtons. Hint: apply Newton's 2nd law to the book, and set the acceleration equal to zero, since it is not moving! P

You can hold your 2.5 kg textbook against the wall, preventing it from slipping down, if you press your hand against it horizontally. Suppose the coefficient of static friction between the book and the wall is 0.50, and there is no friction between your hand and the book. What minimum force do you need to apply to keep the book from slipping down?
A block of weight w is suspended from a rope tied to two other ropes at point O. One rope ishorizontally attached to a wall and the other is fastened to the ceiling. The angle betweenceiling and the rope is 60°. What are the tensions in each of the ropes? Assume the weights ofthe ropes and the knots are negligible. If the weight of the block is 100 N, what is the tension inthe ceiling rope?
Can you check my homework? Im sure I got the right answer, would the force of the tibia be -2984N instaead of positive? thank you
A 12.1 kgkg box sits on a horizontal table. A string with tension 30.6 NN pulls on the box to the right, but static friction between the box and the table prevents the box from moving. The coefficient of static friction between the box and the table is 0.43. What is the magnitude of the static friction force on the box?
Choose the coefficient of friction wisely. Relevant information is given in the textbook. a. What is the maximum frictional force in the knee joint of a person who supports 70.0 kg of her mass on that knee? Fmax 686.7 XN b. During strenuous exercise it is possible to exert forces to the joints that are easily ten times greater than the weight being supported. What is the maximum force of friction under such conditions? (The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pain.) Fmax = N
A push of magnitude P acts on a box of weight W as shown in the figure. The push is directed at an angle 0 below the horizontal, and the box remains a rest. The box rests on a horizontal surface that has some friction with the box. The normal force on the box due to the floor is equal to: O W + P cos 0. O W + P sin 0. OW-P sin 0. O W + P. O W. W 0 P

A student's head is bent over her physics book. The head weighs P = 25.6 N and is supported by the muscle force Fm exerted by the neck extensor muscles and by the contact force Fc exerted at the atlantooccipital joint. Given that the magnitude of Fm is 60.0 N and is directed 35.0° below the horizontal. PN Find the magnitude of the contact force F. . |N
You can hold a book against the wall, preventing it from sliding down, if you press your hand against it. Suppose the coefficient of static friction between the book and the wall is 0.450, but there is no friction between your hand and the book. The mass of your book is 3.75 kg. (a) What minimum force do you need to apply to keep the book from slipping down the wall? Give your answer in units of Newtons. Assume you are applying the force horizontally. (b) Now suppose you are pushing the book at an angle of 37.5 ̊ above the horizontal. Now what is the minimum force you need to apply to keep the book from slipping down the wall? Give your answer in units of Newtons.
Ed and Al are pushing on a couch as shown in the picture and it doesn't slip. EC Ec Ed is pushing with a force of 362.8 N at an angle of 0 = 50.3 degrees with respect to the vertical and Al is pushing with a force of 126.8 N at an angle of o = 29 degrees with respect to the horizontal. If the couch has a mass of 98 kg and the coefficients of static and kinetic friction between the couch and the floor are ug = 0.52, and u = 0.39, what is the magnitude of the force of friction exerted by the floor on the couch?
