*86. mmh The drawing shows a large cube (mass = 25 kg) being accel- erated across a horizontal frictionless surface by a horizontal force P. A small cube (mass = 4.0 kg) is in contact with the front surface of the large cube and will slide downward unless P is sufficiently large. The coefficient of static friction between the cubes is 0.71. What is the smallest magnitude that P can have in order to keep the small cube from sliding downward? Hs = 0.71 Frictionless

i'm doing chapter 4 problem 12p in the college physics 11th edition text book. On bartleby it says that "total force along the x axis is fx= f1sin30degrees - f2sin10degrees" my question is that wouldnt it be the cosine since it is the x axis and not sin?? i put a image below

QS In what direction does the tension force always point? Q9 Why is the tension force always a pull and never a push?

Perpendicular to a Surface: Normal Force, FN Activity 4 A book resting on a table does not move. According to ewton's First Law, the net force on the book must be zero since the book is not moving. The force that explains why books do not fall through tables is called the normal force FN. It is a perpendicular contact force exerted by a surface. In the drawing at the right, a book is sitting on the table. The book is not moving, so the net force on it must be zero. FN Fg Q11 How does the table “know" how much normal force to exert as the weight of the object placed on top of it changes?
Could someone please explain this to me? Thank you!
x Incorrect The force P is applied to the 30-kg block when it is at rest. Determine the magnitude and direction of the friction force exerted by the surface on the block if (a) P = 0, (b) P = 85 N, and (c) P = 131 N. (d) What value of P is required to initiate motion up the incline? The static and kinetic coefficients of friction between the block and the incline are us = 0.18 and µk = 0.12, respectively. The friction force is positive if up the incline, negative if down the incline. %3D P 30 kg 18° H, = 0.18 H = 0.12 12 Answers: (а) F 3D N (b) F (c) F = (d) P =
