Problem 11.024 - Particle motion: velocity-dependent acceleration NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The acceleration of a particle is defined by the relation $a = -k\sqrt{v}$, where k is a constant. Know that x = 0 and v= 81 m/s at t = 0 and that v= 38 m/s when x = 22 m. Problem 11.024.a - Obtaining position from velocity-dependent acceleration by integration Determine the velocity of the particle when x = 20 m. The velocity of the particle is m/s.
