Calcular la velocidad tangencial y la velocidad angular de un movil que describe una circunferencia de 18 centimetros de radio en 0,8 segundos

1.41 m/s, 7.85 rad/s

Explanation:

We can start by calculating the tangential velocity, which is given by:

where

r = 18 cm = 0.18 m is the radius of the circumference

T = 0.8 s is the period

Substituting,

Now we can also calculate the angular velocity,  which is given by:

where again,

T = 0.8 s is the period

Substituting,
