Expert Answer

                                      

 

We know that,

    

or  -----------------1

As v = u + gt

    v= 0 + gt                                (because u =0)

      v = gt      ---------------------2    

In Δ OPQ,

 =       -----------3

putting the values of v and from eq. 2 and 3, in eq.1, we get

 =  mgtxo
