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
-
4.55ms-1
- 12.00ms-1
- 30.00ms-1
- 50.00ms-1
The correct answer is: A
Explanation
\(M_1V_1 + M_2U_2 = V(M_1 + M_2)\)5 x 10 + 6 x 0 = V(5 + 6)
V = \(\frac{50}{11} = 4.55\)m/s
