Answer:
Applying the law's theory and utilizing the equation of momentum ie. p=mv
Explanation:
The law of conservation of linear momentum states that the momentum in a <em>closed</em> system remains constant. Because a collision is inelastic, this proves that the system is closed. So the equation of momentum is p=mv, p is momentum, m is mass and v is velocity.
Because the momentum is conserved, the momentum (p) before the collision should be equal to the p after the collision, so we can equate them and solve for the unknown:
p=m.v
p(before) = p(after)
m(before) x v(before) = m(after) x v(after)
using this equation, you solve it and this helps you solve collision problems.
