Apple hits the surface with speed 16.2 m/s
The angle made by the apple velocity with normal to the incline surface is given as 20 degree
now the component of velocity which is parallel to the surface and perpendicular to the surface is given as
so here we have
<em>so its velocity along the incline plane will be 5.5 m/s</em>
