1. The problem statement, all variables and given/known data
A wheel of radius R=50cm rolls along the ground with velocity V=2m/s. A pebble released on top of the wheel so that it is instantaneously at rest on the wheel. The co-efficient of friction between wheel and pebble is μ=1. The pebble starts to slide down when it has rotated through angle θ with the vertical axis.
Calculate θ.
2. Relevant equations
Absolutely No idea
3. The attempt at a solution
