Which statement concerning a wheel undergoing rolling motion is true
(a) The angular acceleration of the wheel must be zero m/s2.
(b) The tangential velocity is the same for all points on the wheel.
(c) The linear velocity for all points on the rim of the wheel is non-zero.
(d) The tangential velocity is the same for all points on the rim of the wheel.
(e) There is no slipping at the point where the wheel touches the surface on which it is rolling
this is my attempt
a) IDK = I don't know cause I don't know if this wheel is at a constant velocity, should I assume this wheel is going at a constant velocity?
b) IDK = I don't know cause I don't know if this wheel is at a constant velocity, should I assume this wheel is going at a constant velocity?
c) NO = linear velocity should be at some number at each point
d) YES = I think the tangential velocity is the same assuming this wheel is at constant velocity
e) No - there has to be slipping right? common sense RIGHT?
I guess I first need to know if this wheel is going at a constant velocity, am i totally out there?
