Choose the correct alternative regarding pure rolling of a solid sphere on horizontal surface

21. Kinematics of Body in Pure Rolling: (i) Velocity: (ii) Acceleration: 22. Rolling with Slipping: Case-1: v cm > ω R. Note: The friction will be kinetic in nature & its magnitude can be determined using f k = μ k N. Direction will be opposite to v cm (because the point of contact A is moving forward w.r.t. ground) (This is how brakes stop a car) Case-2: v cm < ω RWebSo, option C is correct. Also, due to this torque, the pure translational motion of the motion is converted to pure rolling motion. For pure rolling, the point A which is in contact with the surface must be at rest on the surface. From the above figure, this implies that v = ω R. This means that the velocity of the point (A) is equal to zero. iron wolf A frictional force acting on sphere is f = μmgcosθ B f is dissipative force C friction will increase its angular velocity and decrease its linear velocity D If θ decreases, friction will decrease Solution: In case of pure rolling, f = 1+ ImR2mgsinθ (upwards) ∴ f ∝ sinθ Therefore, as 0 decreases force of friction will also decrease. citadel basketball roster

Rolling Without Slipping Rolling without slipping commonly occurs when an object such as a wheel, cylinder, or ball rolls on a surface without any skidding. To define such a motion we have to relate the translation of the object to its rotation. For example, let's consider a wheel (or cylinder) rolling on a flat horizontal surface, as shown below.Enter the email address you signed up with and we'll email you a reset link.
