A projectile is fired at an angle `theta` with the horizontal. Find the condition under which it lands perpendicular on an inclined plane inclination `alpha` as shown figure.

Find range of projectile on the inclined plane which is projected perpendicular to the incline plane with velcoity 20m//s as shwon in figure.

A very heavy box is kept on a frictionless incline plane inclined at an angle theta from the horizontal. Box is having an another frictionless incline plane, inclined plane as shown in the figure. A block of mass m is kept on this inclined plane inside the box. Acceleration of block w.r.t. box is
