Answer:
Step-by-step explanation:
the displacement of the particle is given by
The rate of change of position gives the value of velocity.
So, v = ds/dt
Differentiate the position function with respect to time.
Now, at t = a
v = -18/a³ m/s
At t = 1
v = - 18 m/s
At t = 2
v = - 18 / 8 = - 2.25 m/s
At t = 3
v = - 18 / 27 = 0.67 m/s
