Awheel turns through an angle of 188 radians in 8.0 s; and its angular speed at the end of the period is 44 rad/s. if the angular acceleration is constant, what was the angular speed of the wheel at the beginning of the 8.0 s interval?

3 rad/s

Explanation:

= Final angular velocity = 44 rad/s

= Initial angular velocity

= Angle of rotation = 188 radians

t = Time taken

Angular displacement is given by

The initial velocity is 3 rad/s

answer: i pick a

explanation:

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
