Question

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?

Answer 1

Solution:

ω=ω_o​+ϵt → ϵ = $\frac{\omega}{t}$=$\frac{5}{10}$= 0.5 ($\frac{rad}{s^2}$)

Answer:

Angular acceleration of a ball is 0.5 $\frac{rad}{s^2}$
