The kinetic energy (KE) of an object can be calculated using the formula:

KE = 1/2 * m * v^2

where:
m is the mass of the object,
v is the speed of the object.

In this case, the kinetic energy (KE) is given as 121 Joules and the mass (m) as 66 kg. We need to find the speed (v).

Rearranging the formula to solve for v gives:

v = sqrt((2*KE)/m)

Substituting the given values into this formula gives:

v = sqrt((2*121 J)/66 kg)

v = sqrt(242/66)

v = sqrt(3.67)

v = 1.92 m/s

So, the cat is moving at a speed of approximately 1.92 m/s.
