Water flow along a horizontal pipe of which the cross sections are not constant. The pressure is 1 cm of mercury where the velocity is 0.35m/s find the pressure at a point where the velocity is 65`cm/s`

A liquid is flowing through a horizontal pipe of varying cross-section.The velocity of flow is 25 cm/sec at a point where the diameter of the pipe is 5 cm. What will be the velocity of flow at another point where the diameter is 1 cm.

A steel ball of mass m is initially at rest on a horizontal frictionless surface. It is struck head on by another steel ball of mass 2m travelling with a velocity of 50 cm/s. Calculate the velocities of the two balls after a collision assuming it to be elastic.

A ball is projected horizontally with a velocity of magnitude 5 m/s. Find its position after 1/4 sec:

An aeroplaine is flying horizontal with a constant velocity of 200m/s at height of 2000 m. If a bomb dropped from the plane is to hit the target, find the distance from the target at wich the bomb is released. G= 9.8 m/ s^@
