Answer:
Explanation:
Let the child is moving with speed same as the speed of water flow
So here the position of child with respect to flow must be zero
And if the boat start at an angle with the vertical
so its relative speed with flow of water is given as
now the time to reach the child is given as
so now we have
So the time to catch the child is given as
So distance moved by it in 0.104 h
distance moved by the boat in upstream direction given as
In y direction the displacement of boat is
net displacement of the ball is given as
