The radius of the disk is 0.8 m. Determine the magnitudes of the velocity and acceleration of point A on the rim of the disk when $t = 0.5$ s. https://www.youtube.com/embed/ybqklzCQjJ4 2026-07-25T11:40:43.780Z yes no https://doassignment.ca/videos/problem-16-2-engineering-mechanics-dynamics-hibbeler-14th-edition-qyk7dswdf3s 2026-07-25 https://i.ytimg.com/vi/QYK7dSWdf3s/mqdefault.jpg Problem 16-2: Engineering Mechanics- Dynamics (Hibbeler 14th Edition) The angular acceleration of a disk is defined by $\alpha = 3t^2 + 12$ rad/s², where $t$ is in seconds. The disk is originally rotating at $\omega_0 = 12$ rad/s. Determine the magnitude of the velocity and the normal and tangential components of acceleration of point A on the disk when $t = 2$ s. Point A is located $r = 0.5$ m from the center of the disk. https://www.youtube.com/embed/QYK7dSWdf3s 2026-07-25T12:46:12.785Z yes no https://doassignment.ca/videos/problem-16-3-engineering-mechanics-dynamics-hibbeler-14th-edition-cmv46ighfs0 2026-07-25 https://i.ytimg.com/vi/cmv46ighFs0/mqdefault.jpg Problem 16-3: Engineering Mechanics- Dynamics (Hibbeler 14th Edition) A disk originally rotating at $\omega_0 = 12 \ \text{rad/s}$ is subjected to a constant angular acceleration of $\alpha = 20 \ \text{rad/s}^2$. Point A is located at a radial distance of $r = 0.5 \ \text{m}$ from the center of the disk. Determine the magnitudes of the velocity and the normal and tangential components of acceleration of point A at the instant $t = 2 \ \text{s}$. https://www.youtube.com/embed/cmv46ighFs0 2026-07-25T13:24:03.159Z yes no
