Angular acceleration worksheet

A bicycle tire increases its angular velocity from ωo = 4.5 rad/s to ω = 9.5 rad/s, accelerating at a constant rate, in 4.0 s. What is its angular acceleration?

A disc with a radius of 0.50 m rotates at a constant angular acceleration of 3.4 rad/s2. What is its linear acceleration?

A boy pushes, with a constant force, a merry-go-round of radius 5.0 m from rest to an angular velocity of 0.60 rad/s in 5.4 s.

What is the angular acceleration, α?

A disc rotates at a constant angular velocity of 6.28 rad/s. What is the frequency? What is the period?.

What is the angular acceleration of a ball that starts at rest and increases its angular velocity uniformly to 5 rad/s in 10 s?

What is the angular acceleration of a ball with a radius of 0.25 m when its linear acceleration on the surface is 20 m/s2?

A child pushes, with a constant force, a merry-go-round with a radius of 2.5 m from rest to an angular velocity of 3.0 rad/s in 8.0 s. What is the merry-go-round's tangential acceleration?
