Unformatted text preview: is described by the acceleration components : 2 s / m 10 y , x − = = & & & & , with initial conditions: y , x , t o o = = = s / m 12 y , s / m 16 x , o o = = & & . At the point of intersection of the path with ( x  axis ) , determine : [a] the time ,the position, and the magnitude and direction of the velocity and acceleration . [b] the time rate of the change of the magnitude of the velocity. [c] the Cartesian coordinates of the centre of curvature. Drawings are necessary. SOLUTION: 3. A ring starts to slide from point O on a circular arc OA of length ( π 100 s OA = ) meters as shown. If the velocity of the ring is defined by: ) t 2 ( v = m /s , where t is the time in seconds, determine: [a] the time it takes to reach the point A . [b] the acceleration at both points O and A . C O A o 45 o 45 R x...
