This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

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?

a. 0.8
b. 0.9
c. 0.6
d. 1.2
