Explain why a body dropped from rest and another projected horizontally from the same height strike the ground at the same time.

A body slides down a smooth inclined plane when released from the top , while another body falls freely from the same point. Which one will strike the ground earlier?

Show that the path of the body projected in a horizontal direction from a height is a parabola.

Find the angle of projection so that a body when projected has the horizontal range equal to the maximum height attained.

Work Problem related to speed, distance and time Places A and B are 70km apart on a highway. A car starts from A and another car start from B at the same time. If they travel in the same direction they meet in seven hours but if they travel towards each other meet in one hour. What are their speed.

Explain why radio waves can not produce photoelectrons from metals, while ultraviolet rays can.

From the top of a tower 100m in height, a ball is dropped and at the same time another ball is projected vertically upwards from the ground with a velocity of 25ms^-1 . Find when and where two balls will meet.

A ball is dropped from rest at a height 12m.If is loses 25% of its kinetic engeryt of striking the ground,Calculate the height to which it bounces.

Two bodies are projected at an angle theta and (90 - theta) to the horizontal with the same speed. Find the ration of their time of flight.

Three bodies - a ring, a solid cylinder and a solid sphere of same mass and radii roll down an inclined plane from the same height. Which of the three will reach the ground first?
