16. 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 - Di) 750J Din) 1250J Do) 1500J Di) 2500 J

To calculate the actual work done by the worker, we need to consider both the force applied and the distance over which it is applied. The force applied is equal to the weight of the box, which is 500 N. The distance over which the force is applied is the length of the ramp, which is 5.0 m.<br /><br />The actual work done can be calculated using the formula:<br /><br />Work = Force x Distance<br /><br />Substituting the given values:<br /><br />Work = 500 N x 5.0 m = 2500 J<br /><br />Therefore, the actual work done by the worker is 2500 J.
