hi!

Explanation:

Hip hop dancing is thought to have officially begun in New York City during the late 1960s and early 70s. During this time, individuals without professional dance training but with a natural instinct for movement brought dancing to the streets

A. w=16.33 rad/s

B. E_k=182401.576 J

C. P_w=36.48kW

Explanation:

Given

R_w=1.2m , m_w=1.9x10^3 kg , f=2.6Hz

The angular velocity is:

$w=2*\pi *f$

$w=2*\pi *2.6Hz$

w=16.33 rad/s

Kinetic energy

$E_K=\frac{1}{2}*I*w^2$

$I=\frac{1}{2}*m*r^2=\frac{1}{2}*1.9x10^3kg*(1.2m)^2$

I=1368.0(kg*m^2)

$E_k=\frac{1}{2}*1368 (kg*m^2)* (16.33 rad/s)^2$

E_k=182401.576 J

kinetic energy every second so:

P_w=0.2*182401.5276J=36480.3 W

P_w=36.48kW
