A ruler, balanced at its center point, has two coins placed on it, as shown in the figure. (Intro 1 figure) One coin, of mass M_1= 10g, is placed at the zero mark;the other, of unknown mass M_2, is placed at the 4.7 mark. The center of the ruler is at the 3.0 mark. The ruler is in equilibrium; it is perfectly balanced.[IMG]http://i40.tinypic.com/15cj2g9.jpg[/IMG]http://tinypic.com/view.php?pic=15cj2g9&s=5A)Does the pivot point (i.e., the triangle, in the diagram, upon which the ruler balances) exert a force...
Problem 2) The cord passes over a frictionless bend, as shown in the figure, carrying = 40 kg at one end and wrapped around a cylinder of mass M2 50 kg that rolls without slipping on the horizontal surface. The system is released, find the a mass M1 acceleration of mass M1. Hint: Note that the acceleration of the cord on the top of the cylinder is twice the acceleration of the center of the cylinder]
Problem 2) The cord...
Scenario A thin hoop of mass M and radius R is released from rest at the top of a ramp of length L as shown at right. The ramp makes an angle with respect to a horizontal tabletop to which the ramp is fixed. The table top is height H above the floor. Assume that the hoop rolls without slipping down the ramp and across the table. Express all algebraic answers in terms of given quantities and fundamental constants. PARTC:...
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...
A spherical shell is released from rest and rolls down a θ = 28° incline without slipping and reaches the bottom with an angular speed of ω = 32.2 rad/s. The M = 1.5 kg sphere has a radius R = 0.60 m and a moment of inertia given as I = (2/3)MR2. Find the distance Δx that the sphere traveled on the incline in m.
QUESTION 4b The system shown in Figure Q4b consists of rollers A and B, and rod AB of mass 3 kg. The system is attached to a spring with stiffness k 100 N/m. If the roller rolls without slipping, determine the velocity of roller B at the instant when 30°. The system is released from rest when ?-0° at which the spring is compressed by 0.5 m. A constant horizontal force P 10 N acts at point C. Figure Q4b...

The M = 1.5 kg sphere has a radius R = 0.60 m and a moment of inertia given as I = (2/3)MR2. R -AX 0 Find the distance Ax that the sphere traveled on the incline. m
A 305-N solid sphere of radius 0.4 m is released from rest and rolls without slipping from the top to the bottom of a ramp of length 5 m that is inclined at an angle of 25 degrees with the horizontal as shown in the figure below. a. What type(s) of energy does the object have when it is released? Gravitational Potential Energy (GPE) Rotational Kinetic Energy (KE) Translational Kinetic Energy (KE) Both KE and KE, GPE, KE, and KE,...
Q10 A hollow sphere and a hoop of the same mass and radius are released at the same time at the top of an inclined plane. If both are uniform, (1) Which one reaches the bottom of the incline first if there is no slipping? (2) A uniform hollow sphere of mass 120 kg and radius 1.7 m starts from rest and rolls without slipping dow an inclined plane of vertical height 5.3 m. What is the translational speed of...
