Ch.4 Problem 88

87. A particle's centripetal acceleration is ac= 4.0 m/s- at t = 0 s. It is executing uniform circular motion about an axis at a distance of 5.0 m. What is its velocity at t = 10 s? 88. A rod 3.0 m in length is rotating at 2.0 rev/s about an axis at one end. Compare the centripetal accelerations at radii of (a) 1.0 m, (b) 2.0 m, and (c) 3.0 m. 89. A particle located initially at (1.5 j +4.0k)m undergoes a displacement of (2.5 i +3.2 j – 1.2k) m. What is the final position of the particle?
