Q40 of 43 Page 85

An aeroplane is moving with a velocity u. It drops a packet from height h. The time t taken by the packet in reaching the ground will be?

Velocity of aeroplane = u

Height above the ground = h


Let, time taken by the packet to reach the ground = T


We define


Vertical direction as Y axis


Horizontal direction as X axis


Velocity along y axis =


Velocity along x axis =



Total vertical height


Time taken to cover

The potential energy of a particle of mass 1 kg moving in a plane is given by V = 3x + 4y the position coordinates of the point being x and y. If the particle is at rest at (6, 4); then find the magnitude of acceleration speed at which it crosses the y-axis and the coordinate at which it crosses the y-axis.
