A 56.0 kg ice skater spins about a vertical axis by her, Ask an Expert

Academics

Q. Calculate the force of gravity between Earth (mass = 6.0 x10^24 kg) and the moon (mass = 7.4x 10^22 kg). The average Earth-moon distance is 3.8 x10^8 m.

Q. A 56.0 kg ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 1.50 turns each second. The distance from one hand to the other is 1.5 m . Biometric measurements indicate that each hand typically makes up about 1.25 % of body weight.
