Apotters wheel moves from rest to an angular speed of 0.10 rev/s in 32.5 s. assuming constant angular acceleration, what is its angular acceleration in rad/s^2? answer in units of rad/s.

0.019 rad/s²

Explanation:

Given:

ω₀ = 0 rad/s

ω = 0.10 rev/s = 0.628 rad/s

t = 32.5 s

Find: α

ω = αt + ω₀

0.628 rad/s = α (32.5 s) + (0 rad/s)

α = 0.019 rad/s²

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
