Answer :
Answer:
53.57 kg or 54 kg
-.81 m/s
Explanation:
m2=[tex]\frac{v}{vf2} \\[/tex] (2m1) -m1
v1f= [tex](\frac{m1-m2}{m1+m2})v[/tex]
The final velocity of the first stone can be calculated as 2.3 m/s.
What is conservation of linear momentum?
The principle of the conservation of linear momentum states that the momentum before collision is equal to the momentum after collision.
Having said that;
m1u1 + m2u1 = m1v2 + m2v2
But we know that v2 is the same for the two bodies when they stick together.
Hence;
2(16 * 1.5) = (16 * v) + (16 * 0.69)
v = 48 - 11/16
v = 2.3 m/s
The final velocity of the first stone can be calculated as 2.3 m/s.
