When the line of sight is above the horizontal level the angle formed is ____.
When we see an object the image formed on the retina is
A particle of mass m is projected with speed u at an angle theta with the horizontal. Find the torque of the weight of the particle about the point of projection when the particle is at the highest point.
Two vertical poles of heights, 20 m and 80 m stand 50m apart on a horizontal plane. The height (in m) of the point of intersection of the lines joining the top of each pole to the foot of the other, from this horizontal plane is
A man observes that when he moves up a distance c metres on a slope, the angle of depression of a point on the horizontal plane from the base of the slope is 30^0, and when he moves up further a distance c metres, the angle of depression of that point is 45^0dot The angle of inclination of the slope with the horizontal is.
A particle is projected horizontally with a speed u from the top of plane inclined at an angle theta with the horizontal. How far from the point of projection will the particle strike the plane ?
A projectile is fired at an angle of 45 ^ { \circ } with the horizontal. Elevation angle of the projectile at its highest point as seen from the point of projection is
