Two identical books each with k pages are placed on the table in a way that the each page of book A is between the pages of book b. The high half of book B is on top of book A. Given that 1) the coefficient of static friction on the surface of card A is mu; 2) Each page of the book has a mass of m; 3) Book A does not move f
A person holds a bowling ball in his hand with his forearm horizontal. The bowling ball has a mass of 5.10 kg and the mass of the forearm is 1.50 kg. The bicep muscle is attached to the bone of the forearm at a point d=3.00 cm from the elbow joint and the bowling ball is L=35.0 cm from the joint. Model the center of mass of the
Hi. Can someone please walk me through how to do the following problem? A person with a mass of 81 kg and a volume of 0.089 m^3 floats quietly in water. (a) What is the volume of the person that is above water? (b) If an upward force F is applied to the person, the volume above water increases by 0.0018 m^3. Find the fo
Three objects are constructed as follows: A simple pendulum has a length Ls= 3.4 m, A physical pendulum consisting of a thin, uniform rod of length Lr, and a mass M= 9.4 kg suspended from a spring whose force constant is k. All three objects oscillate with the same period. Find the length Lr of the thin rod and also the for
Please see the attached PDF file. I would prefer a solution in PDF format. Thank you!
Using the principle of conservation of energy: (a) determine the speed of 3.00kg object just as the 5.00kg object hits the ground. (b) find the maximum height to which the 3kg object rises. (c) How will this mass as it descends rise the mass up as v=0 (m1 and m2 both have a v=0) (solve for y) I have the answers to (a
See the attached file. Draw a phasor diagram and find the maximum value.
A hydraulic jack has two pistons. The diameters of the larger piston and smaller piston are 15 cm and 1.25 cm respectively.It is necessary to lift a 2000 pound car. How large a force must be applied to the small piston? Now assume that a small piston moves through a distance of 10 cm. By what distance will the large piston move?
SEE ATTACHMENT #1 for a diagram of the springs and both arrangements. Spring A has force constant kA= 60 nt/m. Spring B has force constant kB= 40 nt/m. The two springs attached end to end form a series combination with force constant Ks. The two springs attached side by side so that a force applied to the ends stretches bo
SEE ATTACHMENT #1 for a diagram showing parameters. Frictionless block M1 = 3.6 kg, is connected by a cord to block M2 = 7.5 kg. They are placed on a plane which is at angle b= 25 degrees. The coefficient of friction f = .45 between M2 and the plane. Find the tension in the cord as they slide down.
A 3gm bullet with a speed of 300m/sec is fired on a 400gm block initially at rest. The bullet passes through the block and as a result the block begins to move with a speed of 1.5m/sec in the original direction of the bullet. Find the speed of the bullet after it has passed through the block.
Given two guitar strings' lengths and relative densities, find information about their frequencies and tensions. The thinnest string on a certain guitar has a linear density one fifteenth the linear density of the thickest string. Both strings are the same length, L= .64 m. NOTE: On a musical scale a note one octave higher
Archimedes' principle applied to a floating block in turpentine gives density of liquid. The same block, held stationary submerged by a metal block. A block whose mass is Mb= 5.22 kg and density Db= 870 kg/m^3 floats in turpentine whose density is Dt with .004 m^3 of the block submerged. PART a. find the density of the tu
