I don't know if anyone solves physics problems here, but I havn't done this in over a year and can't concentrate right now so I need help. A 1.2 kg book is given a shove at 2.0 m/s. It slides across the table coming to a stop ).67 metres later. a) what is the magnitude of the force that stops the book? b) What is the coefficient of kinetic friction between the book and table and c) If released at the same speed, would a heavier book slide the same distance? Explain for C i think yes because even though there is more force moving, for friction will be acting against it. for b I got 0.3 by dividing the acceleration(-3.0) by (-9.8), im unsure how to get a though.
