Question

A constant torque of 1000 Nm turns a wheel
of of M.I 200kg m about an axis through
centre. The angular velocity after 3s is
2) 22 rad s
4) 60 rad s 1
1) 15 rad s!
3) 28 rad s
2TL​

Answer 1

Answer:

We know that T=Iα

1000=200×α⇒α=5rad/s

2

now we know ω=ω

o

+αt, andω

o

=0

ω=5×3=15 rads
