Two small boats are 10m apart on a lake. Each pops up and down with a period of 4.0 seconds due to wave motion on the surface of water. When one boat is at its highest point, the other boat is its lowest point. Both boats are always within a single cycle of the waves. The speed of the waves is:

Twp boats are moving along perpendicular paths on a still take at right. One boat moves with a speed of 3 ms^(-1) and the other boat moves with a speed of 4 ms^(-1) in the directions such that they collide after some time. At t=0, the boats are 300 m apart. Two boats will collide after time ______.

At a harbour, a boat is standing and wind is blowing at a speed of sqrt(2)m//sec. due to which , the flag on the boat flutters along north - east. Now the boat enters in to river, which is flowing with a velocity of 2m//sec . Due north. The boat starts with zero velocity relative to the river and its constant acceleration relative to the river is 0.2m//sec^(2) due east. In which direction will the flag flutter at 10 seconds ?
