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.
