For a vertical spring launcher is attached to the top of a block and a ball is placed in the launcher, the position of the ball will be behind the box
<h3>What will be the position of the ball relative to the spring launcher?</h3>
Generally, the equation for the conservation of momentum principle is mathematically given as
(M+m) V1 = M*V2
Therefore, with the ball moving forward we have that; the ball at top it wii be behind the box,
