Problems on relative motion between two projectile projected
A cannon fires successively two shells with velocity ; the first at the angle and the second at the angle to the horizontal, the azimuth being the same.
Neglecting the air drag, the time interval(in seconds) between firings leading to the collision of the shells: (Take and Round-off your answer to the nearest integer.)
Let the shells collide at the point . If the first shell takes
to collide with second and be the time interval between the firings, then
................(1)
and
.............. (2)
From equation (1) ...................................(3)
From equations (2) and (3)
as
