A board rides on two driving drums. At the instant shown (*see attached), the board has the acceleration noted. If the board is not slipping on the drums and the total acceleration of the drum contact points is 3m/s[squared], the velocity in m/s of the board at this instant is closest to which answer choice?
*Please see attachment for diagram and figures.
Radius of drum r = 0.25 m
Because, at the point of contact,
acceleration = sqrt(tangential acceleration sqare + square of ...
This solution is provided in 107 words. It uses radius, acceleration and step-by-step calculations to find velocity.
