Q1. A 52.0 kg ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.0 turns each second. The distance from one hand to the other is 1.50 m. Biometric measurements indicate that each hand characteristically makes up about 1.25 % of body weight. What horizontal force should her wrist exert on her hand?
Q2. A horizontal rope is tied to a 46.00 kg box on frictionless ice. What is the tension in the rope if:
The box is at rest?
The box moves at a steady v_x = 4.40 m/s?
The box v_x = 4.40 m/s and a_x = 6.00 m/s^2?
