Show that there are two angles of projection for which the horizontal range is the same.

For given value of u, there are two angles of projection for which the horizontal range is the same. the sum of the maximum heights for these two angles is

There are two angles of projection for which the horizontal range is the same. Show that the sum of the maximum heights for these two angles is independent of the angle of projection.

A body is thrown at an angle alpha to the horizontal with initial velocity v_0 .Assuming air drag to be negligible , find (i)the time of motion, (ii)maximum height of ascent and the horizontal range, (iii)the angle of projection at which they are equal , (iv)the angle of projection at which the horizontal range is maximum and the angle at which the vertical range is maximum.

Find the angle of projection for which the horizontal range and the maximum height are equal.

Find the angle of projection at which horizontal range and maximum height are equal.

Show that the horizontalrange is same for a projectile whether theta is the angle of projection with the horizontal or with the vertical.

two particles are projected upwards with the same initial velocity v_(0) in two different angles of projection such that their horizontal ranges are the same. The ratio of the heights of their horizontal ranges are the same. The ratio of the heights of their highest point will be

During a projectile motion if the maximum height equal the horizontal range, then the angle of projection with the horizontal is :

A body is projected at an angle theta with the horizontal. Derive an expression for its horizontal range. Show that there are two angles theta_(1) and theta_(2) projections for the same horizontal range, such that theta_(1)+theta_(2)=90^(@) .

Two particles are projected with same velocity but at angles of projection 35 and 55 then their horizontal ranges are in the ratio of
