3) An Amazon package from rest slides down a ramp of 25.0 steep. The coefficient of friction of the 2 surfaces is 0.210. Calculate the acceleration of the package. (Ans= 2.3 m/s?) b) The package continues sliding on a horizontal surface as it is off the ramp. Assume that the coefficient of friction between the surfaces stays the same. Sketch a graph of speed v vs. time for the package (including its motion on the ramp), indicate the time at which it leaves the ramp
