Problem

A particle can be thrown at a constant speed at different angles. When it is thrown at

15^\circ

with the horizontal, it falls at a distance of

10\,\text{m}

from the point of projection. For this speed of the particle, match the following columns.

Column I	Column II
(a) Maximum horizontal range possible with this speed	(p) $10\,\text{m}$
(b) Maximum height possible with this speed	(q) $20\,\text{m}$
(c) Range at $75^\circ$	(r) $15\,\text{m}$
(d) Height at $30^\circ$	(s) None of the above
