# a stone is projected from point a with speed u making an angle 60 degrees with the horizontal.the fixed inclined surface makes an angle 30 degrees with the horizontal.the stone lands at b after time t.then the distance ab=

Dear Student,

Consider the situation as shown in the figure below.

Let a particle be projected up with a speed u from an inclined plane which makes an angle α with the horizontal velocity of projection makes an angle θ with the inclined plane.

The equation for the range on an inclined plane is,

Now according to the given information in the question,

Therefore, the range on the inclined plane. In the given question ab is,
