Answer:
The angular velocity, clockwise
Explanation:
The mass of the man, m = 72 kg
The center of mass of the man will be at the middle of his body, particularly around his abdomen.
Height of the center of mass, h = 0.71 m
The speed of the man, v₁ = 1.35 m/s
Moment of inertia about the ankle joint, I = 66 kg/m²
Based on the principle of conservation of angular momentum (about the ankle joint):
Angular momentum before impact = Angular momentum after impact
Angular momentum before impact = -mv₁h
Angular momentum before impact = -(72 * 1.35 * 0.71)
Angular momentum before impact = -69.012 kg m²/s...............(1)
Angular momentum after impact =
Angular momentum after impact = .................(2)
The angular velocity, clockwise
