Q1. The 1994 Winter Olympics included the aerials competition in skiing. In this event skiers speed down a ramp that slopes sharply upward at the end. The sharp upward slope launches them into the air, where they perform acrobatic maneuvers. In the women's competition, the end of the typical launch ramp is fixed 65° above the horizontal. With this launch angle, the skier attains a height of 15.0 m above the end of the ramp. What is the skier's launch speed?
Q2. While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0° banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and road to keep the tires from slipping as you negotiate the curve?
