A projectile is fired with velocity making an angle `theta` with the horizontal. Show that it follows a parabolic trajectory. Obtain an expression for the maximum height attained by it.

A body is projected with a velocity u in a direction making angle theta with the horizontal. Show that path of the projectile is a parabola. Find the maximum heighth reached, the time of flight and horizontal range.

Show that maximum horizontal range is 4 times the maximum height attained by the projectile.

Two polaroids are set in corossed positions.A third polaroid is placed between the two making an angle theta with the pass axis of the first polaroid.Write the expession for the intensity of light trnasmitted from the second polaroid .In what orientations will the transmitted intenesity be maximum.

When a projectile os projected at an angle with the horizontal, find the angle of projection for its maximum horizontal range and find the correspondg height achieved by the projectile?

There is a crater of depth R/100 on the surface of the moon (radius R). A projectile is fired vertically upwards from the crater with velocity, which is equal to theescape velocity v from the surface of the moon. Find the maximum height attained attained by the projectile.

A projectile is fired at an angle of 45^@ with the horizontal.Elevation angle of the projectile at its highest piont as seen from the point of projection is :

A body P of mass m is thrown with velocity u at an angle 30^@ to the horizontal and another body Q is of teh same mass be projected with velocity u at an angle 60^@ to the horizontal .Find the ratio of the horizonta range nd maximum heights of P and Q.
