To find the speed of the object, we can use the formula for kinetic energy:Kinetic Energy = 1/2 * mass * velocity^2Given:Kinetic Energy = 25 JMass = 34 kgWe need to find the velocity.Rearranging the formula, we get:Velocity = sqrt(2 * Kinetic Energy / mass)Substituting the given values:Velocity = sqrt(2 * 25 J / 34 kg)Velocity = sqrt(50 J / 34 kg)Velocity = sqrt(1.47 m^2/s^2)Velocity ≈ 1.21 m/sTherefore, the object is moving at a speed of approximately 1.21 meters per second.
