in vertical direcn. eqns.
h = usin45 * t – 0.5gt^2....................(1)
in horizontal direcn.
d1 = ucos45 * t......................(2)
Also,
again for second part distance apply same formulaes for same height h in vertical and d2 distance in horizontal direction.
and solve the 4 eqns. and get the values.
