Question
Please answer the below question.
You have a level track. You push a cart with mass = 0.76[kg]. You measure the initial velocity to be 0.58[m s6-1]. 2 seconds later, you measure the velocity to be 0.435[m s^-1]. What is the work (reported in mJ) that friction did on the cart? Use three sig. figs, or N/A if not enough information is given, such as change in position! Remember, that if the system gains energy, then positive work is done; otherwise the system loses energy rightarrow work done on systemExplanation / Answer
Answer is : NA ,
Because of to calculate the workdone by friction ,the coefficient of kinetic friction must be given,
