A man can row a boat with 4km/h in still water, if he is crossing a river where the current is 2 km/h. (a) In what direction will his boat be holded, if he wants to reach a point on the other bank, directly opposite to starting point? (b) If width of the river 4km, how long will the man take to cross the river, with the condition in part (a)? (c) In what direction shou ld he heat the boat if he wants to cross the river in shorest time and what is this minimum time? (d) How long will it take him to row 2 km up the stream and then back to his starting point?

A man of mass m runs without sliding from rest from one end of a boat of mass M and length l with an acceleration a relative to the boat. If the friction between water and boat is neglected find the a. acceleration of CM of the system (M+m) b. acceleration of the man and boat c. position of man at the time when he reaches to other end of the boat d. frictional force e. work done by friction on boat. f. total work done by friction. g. velocities of man and boat when the man reaches other end of the boat. h. work down by man

With reference to the given figure, a man stands on the ground at point A, Which is on the same horizontal plane as B, the foot of the vertical pole BC. The height of the pole is 10 m . The man's eye is 2 m above the ground. He observes the angle of elevation of C, the top of the pole, as x^(@) , where tan x^(@) = (2)/(5) . Calculate : angle of elevation of the top of the pole when he is standing 15 metres from the pole. Give your answer to the nearest degree.

AB is a vertical pole with B at the ground level and A at the top. A man finds that the angle of elevation of the point A from a certain point C on the ground is 60o . He moves away from the pole along the line BC to a point D such that C D""=""7""m . From D the angle of elevation of the point A is 45o . Then the height of the pole is (1) (7sqrt(3))/2 1/(sqrt(3)-1)m (2) (7sqrt(3))/2 sqrt(3)+1m (3) (7sqrt(3))/2 sqrt(3)-1m (4) (7sqrt(3))/2 sqrt(3)+1m

The man's eye is 2 m above the ground. He observes the angle of elevation of C, the top of the pole, as x^(@) , where tan x^(@) = (2)/(5) . Calculate : the distance AB in metres ,

In a lake, stream direction is as shown in the figure. A man starting from the point P on the bank wants to move to otherside of the bank in minimum time , so which direction he must travel ? A. along PQ B. along PR C. In a direction in-between PQ and PR D. in all cases he would reach at the same time

A cross between a normal couple resulted in a son who was haemophilic and a normal daughter. In course of time, when the daughter was married to a normal man, to their surprise, the grandson was also haemophilic. a) Represent this cross in the form of pedigree chart. Give the genotypes of the daughter and her husband. b) Write the conclusion you draw of the inheritance pattern of this disease.

A ,man wishing to cross a river flowing with velocity u jumps at an angle theta with the river flow. (a) Find the net velocity of the man with respect to ground if he can swim with speed v in still water. (b) In what direction does the boat actually move ? ( c) Find how far from the point directly opposite to the starting point does the boat reach the opposite bank, if the width of the river is d .

A man in a boat crosses a river from point A. If he rows perpendicular to the banks he reaches point C (BC = 120 m) in 10 min. If the man heads at a certain angle alpha to the straight line AB (AB is perpendicular to the banks) against the current he reaches point B in 12.5 min. Find the width of the river w, the rowing velocity u, the speed of the river current v and the angle alpha . Assume the velocity of the boat relative to water to be constant and the same magnitude in both cases.

A man wishes to estimate the distance of a nearby tower from him. He stands at a point A in front of the tower C and spots a very distant object O in line with AC. He then walks perpendicualr to AC upto B, a distaance of 100m and looks at O and C again. Since O is very distant, the direction of BO is practically the same as AO, but he finds the line of sight of C shifted from the original line of sight by an angle theta = 40^@ ( theta \ "is known as parallax"). Estimate the distance fo the tower C from his original position A.
