Trajectory of particle in a projectile motion is given as
. Here, x and y are in
meter. For this projectile motion match the following with
.
Column I | Column II | ||
(A) | Angle of projection | I. | 20 m |
(B) | Angle of velocity with horizontal after 4 s | II. | 80 m |
(C) | Maximum height | III. | |
(D) | Horizontal range | IV. |
Choose the correct answer from the options given below.

Comparing with the standard equation of Projectile,

We get,
and
Time period of this projectile is 4 s. Hence, After 4 s, Velocity vector will again make an angle of
with horizontal.
So, maximum height,

and horizontal range,
R
