A body of mass 5kg moving with a velocity of 10ms-1 collides with a stationary body of mass 6kg. If the two bodies stick together and move in the same direction after their collision, calculate their common velocity
A
4.55ms-1
B
12.00ms-1
C
30.00ms-1
D
50.00ms-1
Verified Correct Answer: A.
Physical Principles & Numerical Solution
\(M_1V_1 + M_2U_2 = V(M_1 + M_2)\)
5 x 10 + 6 x 0 = V(5 + 6)
V = \(\frac{50}{11} = 4.55\)m/s
