Slipping Definition and 214 Threads

I can't figure out this problem. Pretty much totally lost. It has a hollow, spherical shell with a mass of 2kg, rolls without slipping down an incline of 38 degree's. It wants me to find the acceleration, the friction force, ane the minimum coeffcient of friction needed to prevent slipping...

The board sandwiched between two other boards weighs 95.5 N. If the coefficient of friction between the boards is .663, what must be the magnitude of the comrssion forces (assume horizontal acting on both sides of the center board to keep it from slipping? I have no idea how to do this...

Hi, I don't understand the difference between rolling with and without slipping. To put my question into some kind of context, consider a ball of radius r which rolls to the right along the x (horizontal) axis. The ball is traveling at a constant velocity v and continues rolling until it reaches...

A hollow, thin-walled cylinder and a solid sphere start from rest and roll without slipping down an inclined plane of length 5 m. The cylinder arrives at the bottom of the plane 2.9 s after the sphere. Determine the angle between the inclined plane and the horizontal. Ok, I think I'm close...

A block of a certain material begins to slide on an inclined plane when the plane is inclined to an angle of 14.57°. If a solid cyclinder is fashioned from the same material, what will be the maximum angle at which it will roll without slipping on the plane? I really have no idea where to...

Something I've been noticing a lot is that there are a LOT of students who have somehow slipped through a ton of cracks in the "system" of education. Today I heard something from a grad student that absolutely took the cake. He does tutoring and one day he is helping someone with their intro to...

A coin with a diameter of 2.30 cm is dropped onto a horizontal surface. The coin starts out with an initial angular speed of 18.4 rad/s and rolls in a straight line without slipping. If the rotation slows with an angular acceleration of magnitude 2.17 rad/s2, how far does the coin roll before...

This was a question on a test that I couldn't figure out. You have a hoop, mass M, moment of inertia MR2, and an initial angular velocity ω. It is dropped onto a plane with kinetic coefficient of friction μ. What will be its linear velocity when it stops slipping and rolls away smoothly if it...

A billiard ball of radius "a" is initially spinning about a horizontal axis with angular speed "w" and with zero forward speed. If the coefficient of sliding friction between the ball and the biliard table is "m", (A)find the distance the ball travels before slipping ceases to occur. (B) the...

I am posed the following problem: My work so far is this: For part 1, we solve a system of equations: F_net = M*a = T - F_fr with F_fr the force of friction, Torque_net = I*alpha = T*r + F_fr*R since the torques from the tension and friction operate in the same direction, and a =...

A thin hoop of mass m and radius R is rolling without slipping along a horizontal track. It then encounters a loop of radius r. If the hoop travels fast enough along the horizontal portion of the track it is able to go around the loop without losing contact with it at the top. Find the minimum...

New here, first post. Ok, a block of a certain material begins to slide on an inclined plane when the plane is inclined to a certain angle, theta, giving us tan(theta) = the coefficient of static friction. Now, if a solid cylinder is made out of the material, how would one go about finding...

A rod of mass M and length L, initially standing, falls in such a way that the center of mass experiences only vertical motion. What is the moment of inertia of the rod? I picture the rod as having both translational and rotational motion since it's rotating about an axis through the CM which...

I have no clue how to start solving the question as follows: A box is dropped onto a conveyor belt moving at 1.7 m/s. If the coefficient of friction between the box adn the belt is 0.7, what distance doest the box move before it moves without slipping? (g = 9.8 m/s) What is the horizontal...
