1.	A man of 50 kg is standing at one end on a boat of length 25m and mass 200 kg. If he starts running and when he reaches the other end, has a velocity 2ms^(-1) with respect to the boat. The final velocity of the boat is
Answer» `(2)/(3)ms^(-1)` `(2)/(5)ms^(-1)` `(8)/(5)ms^(-1)` `(8)/(3)ms^(-1)` Solution :`m_(1)u_(1)+m_(2)u_(2)=m_(1)v_(1)+m_(2)v_(2)`
