A bullet is fired vertically upwards with a velocity of 120 ms-1.  What is the maximum height reached by the bullet? (g = 9.8 ms-2)

A bullet is fired vertically upwards with a velocity of 120 ms-1.  What is the maximum height reached by the bullet? (g = 9.8 ms-2) Correct Answer 734.69 m

The initial velocity of bullet u = 120 ms-1

The final velocity of bullet v = 0

According to the 3rd equation of motion,

v2 = u2 - 2gh

0 = (120) - 2 x 9.8 x h

h = 14400 / 19.6

h = 734.69 m

Statement I When a gun is fired, i.e. it placing pushes back with much less velocity than the velocity of the bullet.
Statement II Velocity of the recoiling gun is less because the gun is much heavier than bullet.
According to the Principle of conservation of momentum when the gun is fired, momentum of gun and bullet system remains constant.
