Question

A turntable that is initially at rest is set in motion with a constant angular acceleration a

A. What is the angular velocity after it has completed 1 revolution?

B. How much time will it take to complete 1 revolution?

Answer 1

Explanation:

A. W² - w² = 2 a theta

W² - w² = 2 a n2π

W² - 0 = 2 a x 1 x 2 π

W. = √( 4πa)

B. W = w + at

√(4πa) = 0 + at

t = √(4πa) /a
