To solve this problem, we need to use the equation for kinetic energy:
Kinetic Energy = (1/2) * mass * velocity^2
First, we need to find the velocity of the object. We can use Newton's second law of motion to find the acceleration:
Force = mass * acceleration
Rearranging this equation, we get:
acceleration = force / mass
Plugging in the values given in the question, we have:
acceleration = 4.8 N / 4.4 kg = 1.09 m/s^2
Next, we can use the equation for acceleration to find the final velocity of the object:
velocity = initial velocity + (acceleration * time)
Assuming the initial velocity is 0 m/s (since the object is at rest), and the time is given as 6.4 meters, we have:
velocity = 0 + (1.09 m/s^2 * 6.4 m) = 6.976 m/s
Finally, we can plug the value of velocity and mass back into the equation for kinetic energy:
Kinetic Energy = (1/2) * mass * velocity^2
Kinetic Energy = (1/2) * 4.4 kg * (6.976 m/s)^2
Kinetic Energy = 0.5 * 4.4 kg * 48.66 m^2/s^2
Kinetic Energy = 107.1528 Joules
Therefore, the object has a kinetic energy of approximately 107.1528 Joules.
