ANSWER:
Angular displacement is analogous to distance.
Angular velocity is analogous to velocity.
EXPLANATION:
FOR ANGULAR DISPLACEMENT AND DISTANCE
Angular displacement = theta
theta = s/r
s = linear dispalcement/distance
r= radius.
so ,
linear displacement/distance s = theta * r.
FOR ANGULAR VELOCITY AND VELOCITY
Angular velocity = w
w = v/r
v = velocity
r = radius
so,
velocity v = w * r.
Answer:
ω = 2.9 rad/s, v = 31.7 m/s, α = 0.78 rad/s², a = 91,6 m/s²
Explanation:
I will assume the given equation reads as Ф = 0.39t².
The angular velocity ω is the time derivative of Ф.
ω = 0.78t
The linear velocity v is given by ωr, where r is the radius of the centrifuge.
v = 0.78t r
The tangential acceleration α is the time derivative of ω.
α = 0.78
The radial acceleration a is given by: a = ω²r
a = (0.78t)²r
