2) When released from the position on the hill (at a height of 5 meters, with a speed of 4 m/sec UPHILL), a 3 kg block slides along the path shown, reaching the bottom with a speed of 3.0 m/s. a) How much work does the force of friction do (in J) [note, the coefficient of friction and "shape" of that inclined' surface are not needed, nor given]? b) After it reaches the bottom (with a speed of 3 m/sec as indicated), it continues along the horizontal surface (that has a coefficient of kinetic friction of 0.4) until it stops. Calculate how far it travels on the horizontal surface.
