141286 A particle moves along \(Y\)-axis in such a way that its \(y\)-coordinate varies with time \(t\) according to the relation \(y=3+5 t+7 t^{2}\). The initial velocity and acceleration of the particle are respectively:

141287 An aeroplane moves \(400 \mathrm{~m}\) towards the north, \(300 \mathrm{~m}\) towards west and then \(1200 \mathrm{~m}\) vertically upwards, then its displacement from the initial position is

141289 An object accelerates from rest to a velocity 27. \(5 \mathrm{~m} / \mathrm{s}\) in 10s, then the distance covered after next \(10 \mathrm{~s}\) is :
