Question 1 Report
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?
Answer Details
When two objects collide, the total momentum before the collision is equal to the total momentum after the collision. That is, the momentum is conserved. Therefore, we can write: M1U = (M1 + M2)V Solving for V, we get: V = (M1U)/(M1 + M2) So the correct expression for V is:
Therefore, the answer is the first option.
M1UM1 + M2
