Adisk of radius 14 cm, initially at rest, begins rotating about its axis with a constant angular acceleration of 8.2 rad/s2. what are the following values at t = 10.0 s? (a) the angular velocity of the diskrad/s(b) the tangential acceleration at and the centripetal acceleration ac of a point at the edge of the diskat = m/s2ac = m/s2

a) the angular velocity is ω= 82 rad/seg

b) the tangencial acceleration is a = 1.148 m/s²

c) the centripetal acceleration is ac = 941.36 m/s²

Explanation:

for rotational motion

ω= angular velocity

ωo = initial angular velocity

α= angular acceleration

t = time

R= radius

a= tangencial acceleration

ac = centripetal acceleration

a) ω= ωo + α*t = 0 + 8.2 rad/s2 * 10 s = 82 rad/seg

b) a= α*R =  8.2 rad/s2* 14 cm = 114.8 cm/s² = 1.148 m/s²

c) ac= ω²*R =  (82 rad/seg)² * 14 cm = 94136 cm/s² = 941.36 m/s²

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

d) physical means can be used to separate the components of air.
