11.25 The acceleration of a particle is defined by the relation a = -kv².5, where k is a constant. The particle starts at t 0, with a velocity of 16 mm/s, and when x = 6 mm, the velocity is observed to be 4 mm/s. Determine (a) the velocity of the particle when x = 5 mm, (b) the time at which the velocity of the particle is 9 mm/s. Answer (a) 4.76 mm/s. (b) 0.171 ş.
