A block of 3 kg, initially at rest, is pushed uphill on an incline of 30 degrees over a distance d,. The pushing force is directed horizontally and has a constant magnitude of 35 N. The surface of the incline offers a constant kinetic friction (µk = 0.3). a) Make a FBD for the block and use Newton's 2nd law to find the normal force and the friction. b) Use work-energy approach to calculate how much farther the block moves uphill after we stop pushing (this distance (d,) should be expressed as a proper or improper fraction of the "pushing distance"(d,) – I am not asking for a number!!). Take as your SYSTEM: BALL+INCLINE+EARTH. Make sure to make lists of all the forces that are relevant and to calculate the work done by each of them, as seen in the lectures.
