(i) Can a body in translatory motion have angular momentum? Explain
(ii) Why is it more difficult to revolve a stone by tying it to a longer string than by tying it to a shorter string?

Explanation

Yes, a body in translatory motion shall have angular momentum unless fixed point about which angular momentum is taken lies on the line of motion of body
`|vecL|=rp sin theta`
=0 only where `theta=0^(@) or 180^(@)`
(ii) Ml of stone `I ml^(2)(l to` length of string) l is large, `alpha` is very small
`tau=I alpha`
`alpha=(tau)/(I)=(tau)/(ml^(2))`
If l is large a is very small
`:.` more difficult to revolve.
