radius 50cm at a constant
sрееd of 240rpm finds
its linear speed.
​

Answer 1

hlo mate here is your answer

hope it helps you

Given:

Radius, R=0.5m

Angular acceleration, α=2 rad/s

2

Time, t=2s

Assumption:

Acceleration asked is for a point on the rim.

After 2 s, Angular velocity is given by:

ω=ω

o

+αt

ω=0+2×2

ω=4 rad/s

Centripetal Acceleration is given by, a

c

=ω
