Consider an object `P` on an inclined plane of inclination `beta`.
A shot is fired `O` at an angle `alpha` with horizontal. Find the relation between `alpha` and `beta`, if the shot hits the object horizontally.

A particle is projected up an inclined plane of inclination beta at an elevation prop to the horizontal. Find the ratio between tan prop and tan beta , if the particle strikes the plane horizontally.

A particle is projected up an inclined plane of inclination beta at an elevation prop to nthe horizontal. Find the ratio between tan prop and tan beta , if the particle strikes the plane horizontally.

A trolley containing a liquid slides down a smooth inclined plane of angle alpha with the horizontal. Find the angle of inclination theta of the free surface with the horizontal.

Particle A is relased form a point P on a smooth inclined plane inclined at an angle alpha with the horizontal. At the same instant another particle B is projected with initial velocity u making an angle beta with the horizontal .Both particle again on inclined plane. What is relation between alpha and beta .
