In a collision situation between two spheres where one is called a projectile sphere and the other is a target sphere. Discussions can be made regarding the speed of these spheres after the collision based on the relationship between the masses of these spheres, considering an elastic collision.
From this analyze the correct statements:
I - If the masses of the spheres are equal then the velocity of the projectile sphere after the collision is equal to zero.
II - When the mass of the target sphere is greater than the mass of the projectile sphere, the target sphere will recede after the collision.
III - When the mass of the target sphere is much greater than the mass of the projectile sphere then the projectile sphere recedes with the same modulus as the speed before the collision.
