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
