1. The problem statement, all variables and given/known data How much work is needed to push a 112- kg packing crate a distance of 2.6 m up a frictionless inclined plane that makes an angle of 34 o with the horizontal? Answer: 1595.80 How much work would be required to move the crate the same distance if the coefficient of friction were 0.30? Answer:? 2. Relevant equations W=F*D 3. The attempt at a solution I don't understand the second part is it saying that with friction what would it be? and if so would you not just subtract 0.30*2.6=0.78 and then add that to the first answer? thanks for any help.
