A balloon is moving upwards with velocity 10m/s. It releases a stone which comes down to the ground in 11s. The height of the balloon from the ground at the moment when the stone was dropped is (g=10m/s^2)

A particle has a velocity u towards east at t=0. Its acceleration is towards west and is constant. Let xA and xB be the magnitude of displacements in the first 10 seconds and the next 10 seconds. Then
