A particle is projected from the bottom of an inclined plane of inclination `30^@`. At what angle `alpha `(from the horizontal) should the particle be projected to get the maximum range on the inclined plane.

A particle is projected from the bottom of an inclined plane of inclination 30^@ with velocity of 40 m//s at an angle of 60^@ with horizontal. Find the speed of the particle when its velocity vector is parallel to the plane. Take g = 10 m//s^2 .

A particles is projected from the foot of an inclined plane having inclination 45^(@) , with the velocity u at angle theta( gt 45^(@)) with the horizontal in a vertical plane containing the line of greatest slope through the point of projection. Find the value of tantheta if the particle stikes the plane. (i) Horizontally (ii) Normally

A particle is projected from surface of the inclined plane with speed u and at an angle theta with the horizontal. After some time the particle collides elastically with the smooth fixed inclined plane for the first time and subsequently moves in vertical direction. Starting from projection, find the time taken by the particle to reach maximum height. (Neglect time of collision).
