Question

A 24 kg projectile is fired at an angle of 53 above the horizontal

Answer 1

According to me, your question is

Question: A 24−kg projectile is fired at an angle of 53∘ above the horizontal with an initial speed of 50 m/s. At the highest point in its trajectory, the projectile explodes into two fragments of equal mass, the first of which falls vertically with zero initial speed.

(a) How far from the point of firing does the second fragment strike the ground? (Assume the ground is level.)

(b) How much energy was released during the explosion?

Answer:

(a) 360 m, (b) 10800 J

Explanation:

(a) Explosion will not change the path of CM, therefore CM will fall at a distance equal to range from point of projection.
