A motorboat going downstream overcome a raft at a point A, `tau=60min` later it turned back and after some time passed the raft at a distance `l=6.0km` from the point A. Find the flow velocity assuming the duty of the engine to be constant.

A motor boat going down stream comes over a floating body at a point A . 60 minutes later it turned back and after some time passed the floating body at a distance of 12 km from the point A .Find the velocity of the stream assuming constant velocity for the motor boat in still water.

A float is overcome by a motor boat going downstream at a point A. Thours later it turns back and after some time it passes the float at a distance d km from point A. What is the velocity of stream if the speed of motor remains constant w.r.t. water?

When a boat travels in a river (strictly in a straight line), it can go either in the direction of flow of river (i.e downstream) or in the direction opposite the flow of river (i.e. upstrem ). Thus the boat's actual speed is more than by which it can move in stationary water while travelling downstram (as river's flow speed is added to it) and less while travelling upstream (as the boat moves against the flow of river).Based on the given information answer the following questions A boat going downstream in a following river overcome a raft at a point P. 1 h later it turned back and after some time passed the raft at a distance 6 km from point P. After reversing its direction ,how much time was taken by the boat to meet the raft again ( i.e. 2^(nd) time) ?

A man swimming downstream overcomes a float at a point M. After travelling distance D,he turned back and passed the float at a distance of D//2 from the point M. Then the ratio of speed of swimmer with respect to still water to the speed of the river will be

A swimmer moving upstream passes a float at point P .After two hour, he returns and at this instant it meets the float again at a distance 15km from the point P .If the swimmer velocity in water remains constant, Then find the speed of river flow.

A boat going downstreame took 30 min to go from point A to point B, the return trip took the boat now 60 min. what time will the boat require to cover the the distance from A and B when the motor is turned off speed of baot relative to the water is constant

A stone of mass m is tied to an elastic string of negligble mass and spring constant k. The unstretched length of the string is L and has negligible mass. The other end of the string is fixed to a nail at a point p. Initially the stone is at the same level as the point P. The stone is dropped vertically from point P. (a) Find the distance y from the top when the mass comes to rest for an instant, for the first time. (b) What is the maximum velocity attained by the stone in this drop? (c) What shall be the nature of the motion after the stone has reached its lowest point?

A river is flowing at a speed of 5 km/h in a particular direction. A man, who can swim at a speed of 20 km/h in still water, starts swimming along the direction of flow of the river from point A and reaches another point B which is at a distance of 30 km from the starting point A. On reaching point B, the man turns back and starts swimming against the direction of flow of the river and stops after reaching point A. The total time taken by the man to complete his journey is
