Answer:

The object is moving at 5.48 m/s.

Step-by-step explanation:

The formula for kinetic energy is KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

Using this formula, we can rearrange it to solve for velocity: v = sqrt(2 * KE / m)

Plugging in the values given in the question, we get:

v = sqrt(2 * 75 J / 5 kg)

v = sqrt(30)

v ≈ 5.48 m/s

Therefore, the object is moving at approximately 5.48 meters per second.
