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.
The distance between the boat and raft at a later instant of time t is

A

`(u+v)t`

B

`ut`

C

`vt`

D

`(u-v)t`

Text Solution

Verified by Experts

The correct Answer is:
2

Displacement of raft w.r.t. ground in time t is vt
Displacement of boat w.r.t. ground in time t is `(u+v)t`
So distance between raft and boat at time t is ut

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
