13. A bicycle wheel can be thought of as a ring with a radius of 40 cm and a mass of 3.0 kg. The whee rolls without slipping, first along a horizontal surface and then up an incline, as shown below. The velocity of the center of mass of the wheel on the horizontal portion is vcM 2.0 m/s. How high the incline (vertically) can the wheel roll before coming to rest? A. 0.10 m B. 0.15 m C. 0.20...
Consider a bicycle wheel of mass M and radius R that sits on a flat, level surface, such that the surface is tangent to the wheel. One end of a spring (spring constant, k) is attached to bicycle wheel’s hub, and the other end is fixed to a vertical wall. The spring is horizontal. There is sufficient friction to prevent the wheel from sliding at the point of contact with the surface. When the center of the wheel is directly...

A hoop of mass M = 3 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure. The lack of slipping means that when the center of mass of the hoop has speed v, the tangential speed of the hoop relative to the center of mass is also equal to vCM, since in that case the instantaneous speed is zero for the part of the hoop that is in contact with the...
A bicycle wheel of radius 0.290 m rolls without sliding on a horizontal surface at a constant angular speed of 15.0 rad/s. A piece of gum of mass 5.30 g is stuck to the rim as shown in the diagram. (a) What is the magnitude of the angular momentum of the gum when it is at location A relative to the points indicated below? the center of the wheel. 0.0087 kg-m/s 0.0267 x the point of contact, C What is...
Part Al Select the best answer of the following multiple choice questions (32 Points), just circle your choices Question 1. A meter stick is pivoted at the 0.50-m line. A 6.0 kg object is hung from the 0.15-m line. Where should a 10.0 kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)? A) 0.06-m line B) 0.24-m line C) 0.46-m line D) 0.71-m line E) A 5.0 kg object cannot be placed anywhere on the...
Consider a bicycle wheel that initially is not rotating. A block of mass m is attached to the wheel via a string and is allowed to fall a distance h. Assume that the wheel has a moment of inertia I about its rotation axis Now consider the case that the string tied to the block is wrapped around a smaller inside axle of the wheel of radius rB as shown in (Figure 2) . Find ωB, the angular speed of...
The figure on the right illustrates a ball which is a uniform solid sphere having mass M and radius R. The ball is initially traveling in the positive direction with pure translational motion along a friction-less region of a horizontal surface (i.e. it slips with angular speed ω0-0). The initial translational speed of the ball is Vo. The friction-less region extends to a region having coefficient of kinetic friction Figure for WAH #10 V. Friction Friction-less No longer slipping '...
3. A very thin circular hoop of mass m and radius r is made to roll, without slipping, down a ramp with an angle of inclination (with respect to the horizontal), as shown in the figure below. See Figure 3. Note: The moment of inertia of the thin circular hoop is given by: I houp = mra Consider a system consisting of a ladder with a painter climbing said ladder. The ladder has a length 1 = 5,00 meters and...
Rotational Dynamics Assignment (200 Points) • Due Friday, July 31 at 5:00 pm Equations are in a separate document entitled “Equations for Rotational Dynamics Assignment” • Moments of inertia formulas are provided on the last page of this document • Show all of your work when solving equations. It is not sufficient to merely have a correct numerical answer. You need to have used legitimate equations and algebra. You also need to have correctly used the data. • Units must...
