Problem

In a projectile motion, given

H = \frac{R}{2} = 20

m. Here,

H

is maximum height and

R

the horizontal range. For the given condition match the following two columns.

Column I	Column II
(a) Time of flight	(p) 1
(b) Ratio of vertical component of velocity and horizontal component of velocity	(q) 2
(c) Horizontal component of velocity (in m/s)	(r) 10
(d) Vertical component of velocity (in m/s)	(s) None of the above
