 P: 22 1. The problem statement, all variables and given/known data A 220kg load is lifted 21.0m vertically with an acceleration a=0.150 g by a single cable. Determine: a. the tension in the cable b. the net work done on the load c. the work done by the cable on the load d. the work done by gravity on the load e. the final speed of the load assuming it started from rest. 2. Relevant equations Not sure I wasn't in class 3. The attempt at a solution I was sick with mono for a couple of months and couldn't go to school and the teacher from home and hospital school never taught me any of this, so couls someone please please help?
 P: 1,384 Are you familiar with Newton's laws of motion? If you are you should be able to solve the first one. Though I - or someone else - could simply give you all the equations you might need to use, if you're unfamiliar with the concepts it would ultimately be fruitless: You could do the math but other than equations there would be no significance. Would it be possible for you to make a list of what you already know, and then any explanation necessary can be given?
 P: 22 Well for the first one would you do the mass times the acceleration, because from my book i think that tension equals force correct? but with my home and hospital teacher we never reviewed any of the other topics so im completely lost
