a skier starting from rest down a snow slope that makes 18 degrees with the horizontal. He starts from the height of 8 m. at the bottom of the slope is a 9 m long rough horizontal surface. the acceleration slowing the skier down on the rough patch has a magnitude of .8m/s2. what is the skier's speed when he reaches the end of the rough patch? calculate the time intervals it takes the skier to reach the bottom of...
