I totally do not understand how to do this. I missed this day in class and the teacher hasn't had time to explain it to me. Could someone help?
The efficiency of a pulley system is 73%. The pulleys are used to raise a mass of 58 kg to a height of 3.0 m. WHat force is exerted on the string of the pulley systen if the string is pulled for 18.0 m in order to raise the mass of the required height?
Thanks in advance
