A particle is thrown vertically upwards from the surface of the earth. Let T_(P) be the time taken by the particle to travel from a point P above the earth to its highest point and back to the point P. Similarly, let T_(Q) be the time taken by the particle to travel from another point Q above the earth to its highest point and back to the same in terms of T_(P), T_(Q) and H, is :-

An object is taken from a point P to another point Q in a gravitational field:

A point particle of mass m, moves long the uniformly rough track PQR as shown in figure. The coefficient of friction, between the particle and the rough track equals mu . The particle is released, from rest from the point P and it comes to rest at a point R. The energies, lost by the ball, over the parts, PQ and QR, of the track, are equal to each other, and no energy is lost when particle changes direction from PQ to QR. The value of the coefficient of friction mu and the distance x (=QR) , are, respectively close to:

Does the ray PQ starts from points Q ?

Dr. Bansal needs to determine the distance PQ across a river in and east-west direction as shown in the adjoining figure. He can't measure this distance directly over the water. So, he selects the point S from where a straight line to point Q stays on land so he can mesure distance. he then moves eastward a distance of 400 m from point S to T , so that the line of sight from point T to P cuts the previous line SQ at R. finally with a long measuring tape. he determines that. SR = 250 m, QR= 1250 m Determine if this is enough information to calculate the distance PQ and if so, find PQ and hence find the time taken by a swimmer to cross the river PQ with a uniform speed of 800 m/hr.

A river of width omega is flowing with a uniform velocity v. A boat starts moving from point P also With velocity v relative to the river. The direction of resultant velocity is always perpendicular to the line joining boat and the fixed point R. Point Q is on the opposite side of the river. P, Q and R are in a straight line. If PQ=QR=omega, find (a) the trajectory of the boat, (b) the drifting of the boat and (c) the time taken by the boat to cross the river.
