1. A machine does ( 2500 mathrm{~J} ) of work in ( 1 mathrm{~min} ). What is the power developed by this machine? 2. Calculate the work done by a ( 20 mathrm{~N} ) force applied to a block as shown below, if the block moves a distance of ( d=13 mathrm{~m} ) as a result of the application of this force.

Step 1
To find the power developed by the machine, we need to convert the work done and time taken into the appropriate units and then use the formula for power. Power = Work done / Time taken Given, work done = 2500 J and time taken = 1 min. We need to convert the Show more…
