1.	An object falls from a bridge which is 45m above the water. It falls directly into a small row - boat moving with constant velocity that was 12m from the point of impact when the object was released. What was the speed of the boat?
Answer» Solution :VELOCITY of boat = `V=(s)/(t)` Here, `s=12m` t = time of fall of OBJECT from bridge `=sqrt((2h)/(g))=sqrt((2xx45)/(10))=3s therefore V=(12)/(3)=4ms^(-1)`
