In the figure the rod is rotating with an angular velocity `omega` and the end point A has a velocity `vecv`. Find the angular momentum of the rod about the end point `A` of the rod

A

Velocity of the particle in interval `t=0` to `t=2` sec is in positive `x` direction.

B

Speed of the particle is `1m//s` at `t=3/2s`

C

Distance travelled in the interval `t=0` to `t=2s` is zero

D

Its speed first increases then decreases.
