Question

Two balls are projected
simultaneously in the
same vertical plane from
the same point with
velocities V, and V, at
angles 0, and
,respectively, with the
horizontal .If Vcose, =V, cos 0,
the path of one ball as
seen from the position of
other ball is​

Answer 1

Explanation:

Two balls are projected simultaneously in the same vertical plane from the same point with velocities V1 and V2 with angles θ1 and θ2 respectively with the horizontal. If V1 cosθ1 = V2 cosθ2 the path of one ball as seen from the position of other ball is

1) Parabola

2) Horizontal straight line

3) Vertical straight line

4) Straight line making 45° with the vertical
