A swimmer S is in the sea at a distance dkm from the closest point A on a straight shore. The house of the swimmer is on the shore at distance of the swimmer is on the shore at ukm/h.walk at speed at vkm swin at speed oh on shore should he land so that hhe reaches his house in the shortest time.

The distance (in km) travelled in h hours at a constant speed of 40 km per hour is

If the distance of 200 m is covered in 20 s, then the speed is

Two swimmers leave point A on the bank of the river to reach point B lying right across on the other bank. One of them crosses the river along the straight line AB while the other swims at right angles to the stream and then walks the distance that he has been carried away by the stream to get to point B. What was the velocity u of his walking if both swimmers reached the destination simultaneously? The stream velocity v_0=2.0 km//hour and the velocity v^' of each swimmer with respect to water equals to 2.5km per hour.

Two swimmers leave point A on one bank of the river to reach point B lying right across on the other bank. One of them crosses the river along the straight line AB while the other swims at right angles to the stream and them walks the distance that he has been carried by the stream to get to point B . what was the velocity v_(0) of his walking if both swimmers reach the destination simultaneously? The stream velocity is u and v is the velocity of swimmer in still water.

Two swimmers start at the same time from point A one bank of a river to reach point B on the other bank, lying directly oppostie to point A. one of them crosses the river along the straight line AB, while the other swims at right angles to the stream and then walks the distance, which he has been carried awayby the stream to get to point B. Both swimmers reach point B at the same time. what was the velocity (assumed uniform) of his walking if velocity of both the swimmers in still water is 2.5 km h^(-1) and the stream velocity is 2 km h^(-1) ?

A swimmer swims in still water at a speed =5 km//hr . He enters a 200m wide river, having river flow speed =4km//hr at point A and proceeds to swim at an angle of 127^(@) (sin 37^(@) = 0.6) with the river flow direction. Another point B is located directly across A on the other side. the swimmer lands on the other bank at a point C , form which he walks the distance CB with a speed = 3km//hr . The total time in which he reaches from A to B is

Two point masses m and M are separated bya distance L . The distance of the centre of mass of the system from m is
