Solution

## The correct option is A 20rad/secGiven: when a person throws a meter stick it is found that the centre of the stick is moving with a speed of 10 m/s vertically upwards & left end of stick with a speed of 20 m/s vertically upwards. To find the angular speed of the stick Solution:Let r be the distance between the end point and center of the stickHerer=l2=12mAs per the given criteria,speed of center of the stick, v=10m/sand speed of left end of the stick, VP=20m/sAnd VP=v+rω⟹20=10+12ω⟹ω=20rad/sis the angular speed of the stick
