Assertion: Separation between two bodies moving in the same direction on the ground with same acceleration, will not increase.
Reason: In this case river flow helps to cross the river.

Assertion: To cross the river in minimum time swimmer should swimming in perpendicular direction to the water current. Reason: In this case river flow helps to cross this river.

Assertion: To cross the river in minimum time swimmer should swimming in perpendicular direction to the water current. Reason: In this case river flow helps to cross this river.

Assertion: To cross the river in minimum time swimmer should swimming in perpendicular direction to the water current. Reason: In this case river flow helps to cross this river.

Statement I : The distance between two bodies does not change if they move in the same direction with the same constant acceleration. Statement II : Two bodies moving with the same velocity are at rest relative to each other.

A man can swim with a certain speed, in still water to cross a river to a point directly opposite to the starting point in time t_(0) . When the river flows, he crosses the river directly along the same path in a time t_(1) , If 'd' be the river width, Then the velocity of water current is:

When two bodies move uniformly towards each other, the distance between them decreases by 8 m//s . If both the bodies move in the same direction with the same speeds, the distance between them increases by 4 metre per second. What are the speeds of two bodies ?

Assertion : In case of elastic collision between two objects , speed of approach is same as speed of separation . Reason : In case of elastic collision between two objects , linear momentum of the system remains conserved .

A river of width 100 m is flowing with a velocity of 1.5 m/s. A man start from one end with rest relative the river. He raws with an acceleration of 2 m//s^(2) relative to the river. If the man want to cross the river in minimum time, by how much distance (in meters) will he be drifted (flown) in the direction of river flow during the crossing.
