3. A man pushes a 500-N box up a 5.0-m long ramp. The box was raised a vertical distance of 2.5 m The actual work done by the worker was iii Do 1250 Do 2500 J Do 750J D 1500J

To calculate the actual work done by the worker, we need to use the formula for work:<br /><br />Work = Force x Distance<br /><br />In this case, the force applied by the worker is 500 N and the distance is 5.0 m. Therefore, the actual work done by the worker is:<br /><br />Work = 500 N x 5.0 m = 2500 J<br /><br />So, the correct answer is 2500 J.
