A projectile is projected down an inclined plane with an initial speed v=20m/s in horizontal direction.Inclined plane makes an angle of 37 degree with horizontal If plane of motion makes an angle of 30 degree with line of greatest slope(straight line along inclined horizontal to its plane),find range and time of flight of projectile. Since the question involves visualising things in 3D, i would first want someone to provide a bit of explanation regarding what's going on(honestly speaking, 3D visualization is what pisses me most).Next, i already have a solution of this problem but not much helpful because again most of it depends upon visuAlising things in 3D.So,if someone can provide a mathematical solution of the same (maybe involving a bit of elementary 3D geometry)which could somewhat reduce this 3D visualisation to the barest minimum.Thanks.
