Twin skaters approach each other with identical speeds. Then, the skaters lock hands and spin. Calculate their final angular vel
kherson [118]

Answer:

\omega=3.135rad/s

Explanation:

From the question we are told that:

initial Speed V_1=2.50

Mass m=70.0kg

Center of mass d=0.0.800m\

Generally the equation for angular velocity is is mathematically given by

\omega=\frac{v}{r}\\\\\omega=\frac{2.50}{0.0800}

\omega=3.135rad/s

100 POINTS PLEASE HELP
deff fn [24]

Answer:

Explanation:

Spilling the force of 60N on the rope at an angle θ in x-y direction:

fx = Fcosθ = 60cosθ

fy = Fsinθ = 60sinθ

cosθ and sinθ both vary from 0 to 1 between 0° to 90° but they go in opposite direction:

cos0° = 1 and cos90° = 0

sin0° = 0 and sin90° = 1

sin45° = cos45° = 0.7071

When θ increases from 0° to 90°,

θ=0°, fx = 60cos0° = 60N, fy = 60sin0° = 0N

θ=90°, fx = 60cos90° = 0N, fy = 60sin90° = 60N

θ=45°, fx = 60cos45° = fy = 60sin45° = 42.43N
