A projectile is fired with the velocity v 0 = 2 m s - 1 at an angle 60 o with horizontal. At top of its trajectory, it explodes into three fragments of equal mass. The first fragment retraces the path, second moves vertically upward with speed 3 v 0 2 . The speed of the third fragment (in m s - 1…

Question

A projectile is fired with the velocity v 0 = 2 m s - 1 at an angle 60 o with horizontal. At top of its trajectory, it explodes into three fragments of equal mass. The first fragment retraces the path, second moves vertically upward with speed 3 v 0 2 . The speed of the third fragment (in m s - 1 ) is

Aicharya · Accepted Answer

Let velocity of third fragment be &#8594; V P i &#8594; = P f &#8594; &#8658; 3 m v 0 2 i ^ = &#8722; m v 0 2 i ^ + m 3 v 0 2 j ^ + m v &#8594; v &#8594; = 4 v 0 2 i ^ &#8722; 3 v 0 2 j ^ &#8658; v = 5 v 0 2
