Question
Consider a physical system formed by a symmetrical rigid body with a circular profile of radius R. This rolls without sliding on a horizontal surface.
Which of the following statements is not correct?
a. The velocity at the point of contact of the rigid body with the horizontal surface is zero.
b. The speed of the center of mass of the rigid body is ωR
c. The friction force of the rigid body with the ground is kinetic.
d. The acceleration of the center of mass of the rigid body is αR
a. The velocity at the point of contact of the rigid body with the horizontal surface is zero.
b. The speed of the center of mass of the rigid body is ωR
c. The friction force of the rigid body with the ground is kinetic.
d. The acceleration of the center of mass of the rigid body is αR
Expert Solution
Step 1
Since there is no slipping between ground and body so velocity of point of contact is zero and Vcm = WR
Due to no slipping friction acting is static
So, option C is wrong
