A man floating on a raft in water flowin...

A man floating on a raft in water flowing at 2kmph observes a motor lauch overtaking him at t = 0. Then lauch travels with the speed of 20kmp relative to still water . After travelling for a time of 1 hr , the lauch turns back towards raft.How far from from the original point of crossing do they meet and what is the total time elapsed ?

To solve the problem step by step, we will analyze the motion of both the man on the raft and the motor launch. ### Step 1: Understanding the velocities - The river flows at a speed of 2 km/h. - The motor launch travels at a speed of 20 km/h relative to still water. ### Step 2: Determine the effective speed of the launch Since the river is flowing, we need to find the effective speed of the launch relative to the ground. The launch's speed with respect to the river is: ...

A boat can be rowed in still water at a speed u. The boat is moving downstream in a river in which water flows at a speed v. There is raft floating in water and therefore moving along with water at speed v. Let the boat overtakes the raft at the moment t = 0. Let the boat turns back at time t=t_(0) and starts moving towards the raft. The separation between the raft and boat after a time interval t' measured from the moment of turning back is
