The final speed of the combined masses is 0.186m/s
According to the law of collision, the sum of the momentum of the bodies before the collision is equal to the momentum after the collision.
Mathematically;
m1u1 - m2u2 = (m1+m1)v
- v is the final speed of the combined masses.
Substituting the given parameters;
0.24(0.6) - 0.26(0.2) = (0.24+0.26)v
0.144 - 0.052 = 0.5v
0.092 = 0.5v
v = 0.092/0.5
v = 0.184m/s
Hence the final speed of the combined masses is 0.186m/s

Answer:
m = 500 grams
Explanation:
Assuming that the fulcrum is at the midpoint of a uniform meter stick, the moments about the fulcrum must be equal and opposite.
the 200 g mass makes a moment
200(g)[20] = 4000g gm•cm
the other mass must also create a moment of the same value
m(g)[8] = 4000g
m[8] = 4000
m = 500 grams
