1. A 1310-kg car starts from rest at the top of a driveway 6.46 m long which is sloped at an angle of 20 degrees with the horizontal. If an average friction force of 3350 N impedes the motion of the car, find the speed (in m/s) of the car at the bottom of the driveway.
2 . Esteemed Chinese ski jumper, Li Ping Phar, leaves the jump ramp with an initial speed of 31.7 m/s and a height (relative to the bottom of the ski hill) of 46.4 meters. There is -6610 Joules of energy dissipated due to air resistance during her flight through the air. Determine the speed (in m/s) of her 45.2-kg body the instant prior to striking the ground at the bottom of the hill.
