1. The problem statement, all variables and given/known data Acceleration of an object is described by a function of x, a(x) = bx. (b is a constant 2 sec^-2) 1. If the speed at x=1m is zero, what is the speed at x=3m? 2. How long does the travel from x = 1m to x = 3m takes? 2. Relevant equations chain rule : dr/dt = dr/ds*ds/dt 3. The attempt at a solution I have thought of spring in a simple harmonic motion. But I could not take any further steps... Somebody help me please!
