9) Solve the problem. A particle moves such that its velocity a m/s (meters per second) is related to its displacement x meters by the equation: "(x) = arctan(sin x). for 0 =x= 1. The particle's acceleration is a m/s2. (a) Find the particles acceleration in terms of x. (b) Find the particle's displacement when its acceleration is 0.25 m/s2 (a) Find the particles acceleration in terms of x. (b) Find the particle's displacement when its acceleration is 0.25 m/s2
