Question

the angular speed of force increase 600 rpm to 120 rpm is 20 s . calculate its angular accerleration .....




​

Answer 1

Explanation:

ω=ω

0

+α×t

for t=20sec or 1/3 minutes,

α=1800

From ω

2

=ω

0

2

+2αθ

(1200)

2

=(600)

2

+2×1800×θ

1440000−360000=3600θ

1080000=3600θ

θ=

3600

1080000

=300
