`(i)` Two particles are in projectile motion. The apth of one particle as seen by another particle will be straight line.
`(ii)` In order to cross a river of uniform width `(` flow is also uniform `)` in shortest time, swimmer must swim in perpendicular direction of river flow.

Text Solution

Verified by Experts

The correct Answer is:
`(i)` False `(ii)` True
False There acceleration may be differenct.
True `T=(W)/(V)` to minimize `T,V` will be maximum .
`i.e.,` whole effort of swimmer must towards opposite bank.

A boat can be rowed at 5 m/s on still water. It is used to cross a 200m wide river from the south bank to the north bank. The river current has uniform velocity of 3 m/s due east. (a) In which direction must it be steered to cross the river perpendicular to current ? (b) How long will it take to cross the river in a direction perpendicular to the river flow ? (c) In which direction must the boat be steered to cross the river in minimum time ? How far will it drift ?

  • Two ports, A and B, on a north-south line ar separated by a river of width D. The river flows east with speed u. A boat crosses the river starting from port A. The speed of the boat relative to the river is v. Assume v=2u Q. Suppose the boat wants to cross the river from A to the other side in the shortest possible time. Then what should be the direction of the velocity of boat relative to river?

    A

    `30^@` east of north
    C
    `60^@` west of north
    D
    along north
