# Dynamics Problem - Tangential Acceleration an Velocity

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

#### Solution Preview

Radius of drum r = 0.25 m

Because, at the point of contact,

acceleration = sqrt(tangential acceleration sqare + square of ...
