Given
Freddi fish position as a function of time
x= a/(b+t^2)
can be written as
x = a/b + a/t^2
a)
x is position of the fish , units are meters
so
the units of a ,b are
a ---- m.s^2
b ----- s^2
the time derivative of displacement is velocity
dx/dt = (d/dt)(a/b+ a/t^2)
= -2a t^-3 m/s
c)checking units
a -- --- ms^2
t^-3 ----- s^-3
m s^2*s^-3 = m/s
