A body of mass M1 moving with a velocity U collides with a stationary body of mass M2 and both move with a common velocity V lf linear momentum is conserved, which of the following expressions correctly represents V?
- A. M1 U/M1 + M2
- B. M2 U/M1 + M2
- C. M1 + M2/M1 U
- D. M1 - M2/M1 U
Correct Answer: A. M1 U/M1 + M2
Explanation
M1U + M2 x 0 = (M1 + M2)v V = M1 U/M1 + M2
