Its linear velocity increases constantly from 0 to 7 m/s in 3.4 s. What is its angular acceleration? Correct answer: 7.62527 rad/s2. Explanation: Let : R = 0.27 m, âˆ†v = 7 m/s, and âˆ†t = 3.4 s. v B Ï‰ Consider point B at the bottom of the wheel. It is at rest since there is no slip-ping. Its velocity v B = v âˆ’ Ï‰R = 0 Ï‰ = v R Î± = âˆ†Ï‰. 5.2 m/s, theta = 67.4^@ The most important concept to understand here is that the vertical component of the initial velocity is equal to zero, but that the vertical component of the final velocity will not be equal to zero. At the moment the ball leaves the table, the vertical component of its initial velocity will be equal to its initial velocity. You thus have {(v_(0y) = 0), (v_(0x) = v_0.
