The kinetic energy of an object is described with the formula one half time m times v squaredwhere K is the kinetic energy of the object in joules (J), m is the mass of the object in kilograms (kg), and v is the velocity of the object in meters per second meters per second. What is the velocity of an object with a kinetic energy of 375 J and a mass of 50 kg?

To find the velocity of the object, we can rearrange the formula for kinetic energy:
K = 1/2 * m * v^2
375 = 1/2 * 50 * v^2
375 = 25v^2
v^2 = 15
v = √15 ≈ 3.87 m/s
Therefore, the velocity of the object with a kinetic energy of 375 J and a mass of 50 kg is approximately 3.87 m/s.
