1. The female skater is in the air for about 0.99 seconds. 2. Her initial velocity is vx = 7.1 m/s vy = 4.8 m/s or v = 8.5 m/s at 34 degrees above horizontal 3. Her maximum gravitational potential energy (assuming GPE = 0 at the surface of the ice) is about 567 J 4. Her maximum kinetic energy occurs at the moment she is thrown and the moment before she lands, when her KE = 1734 J
