269827 A bus moves over a straight level road with a constant acceleration a. A boy in the bus drops a ball out side. The acceleration of the ball w.r.t the bus and the earth are respectively

269828 A particle\(P\) moves with speed ' \(v\) ' along \(A B\) and BC, sides of a square ABCD. Another particle \(Q\) also starts at \(A\) and moves with the same speed but along \(A D\) and \(D C\) of the same square ABCD. Then their respective changes in velocities are

269829 A river is flowing from west to east at a speed of\(5 \mathrm{~m} / \mathrm{s}\). A man on the south bank of the river capable of swimming at \(10 \mathrm{~m} / \mathrm{s}\) in a still water wants to swim, across the river in a shortest time. He should swim in a direction
