Question

An ice skater is preparing for a jump with turns and has his arms extended. His moment of inertia is 1.8 kg⋅m2 while his arms are extended, and he is spinning at 0.69 rev/s. Then he simultaneously pulls his arms in and launches himself into the air at 5.3 m/s at an angle of 41∘ with respect to the ice. His moment of inertia in the air is 0.5 kg⋅m2.How long in seconds is the skater in the air? Specify your answer in at least two digits past the decimal point.
