. A ladder of 3m length leans against a wall. Initially the ladder forms a vertical angle of 30° with the wall. If the top of the ladder begins to slide down the wall at constant rate of 20 cm/s, the bottom of the ladder slides away from the wall at rate of 20 cm/s at time 't' seconds. The average velocity of a person halfway up the ladder for the first 't' sec। ques of math
Bhaiya kitna mehnat karte ho aap ❤

Ans-[(3)^1/2 + (2)^1/2]/10 [ ( 2^1/2 -1)i +(2^1/2 - 3)j
