A uniform rod kept vertically on the ground falls from rest. Its foot does not slip on the ground

Water falls from the top of a hill to the ground. Why?

A uniform rod is kept vertically on a horizontally smooth surface at a point O. IF it is rotated slightly and released, it falls down on the horizontal surface. The lower end will remain

A tower of height 15 m stands vertically on the ground. From a point on the ground the angle of elevation of the top of the tower is found to be 30^(@) . What is the distance of the point from the foot of the tower?

A lower of height 15 m stands vertically on the ground. From a point on the ground the angle of elevation of the top of the tower is found to be 30^(@). What is the distance of the point from the foot of the tower?

A rod length 15 m stands vertically on the ground. With one end hinged to the ground. When it falls on the ground such that it rotates without slipping, the velocity of the upper tip on striking the ground is
