Here is the question:
A wheel of radius R rolls along the ground with velocity V. A pebble is carefully released on top of the wheel so that it is instantaneously at rest on the wheel. Show that the pebble will immediately fly of the wheel if V > sqrt(Rg).
What does this mean. In particular, what does instantaneously at rest mean??
