The acceleration of a particle is given by the relation as `a = -kv^(5//2)` , where is a constant. The particle starts at x=0 with a velocity of 16 m/s, and when x = 6, the velocity is observed to be 4 m/s. Find the velocity of particle when x=5m and the time at which the velocity ofthe particle is 9 m/s.

Answer

[4.76 m/s, 0.172 s]
