Answer:
The correct answer is D
Explanation:
The answer is D because the first paragraph of the passage contains a "however" in the middle. This clearly depicts that the author is making an effort to show a different view other than the normal thinking. Furthermore, in the second paragraph of the passage, the author is simply trying to explain the reasons why seals are different and the need for them to forage.
Answer:
Velocity B = 20 m/s
Explanation:
Let the mass and velocity of the first object be A.
Let the mass and velocity of the second object be B.
Given the following data;
Mass A = 50 kg
Velocity A = 10 m/s
Mass B = 25 kg
To find the velocity of mass B;
First of all, we would determine the momentum of mass A;
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
Substituting into the formula, we have;
Momentum A = 50 * 10
Momentum A = 500 Kgm/s
As a result of the collision, momentum of mass A is equal to the momentum of mass B.
Momentum A = Momentum B
500 = mass B * velocity B
500 = 25 * velocity B
Velocity B = 500/25
Velocity B = 20 m/s
Therefore, the velocity of the 25.0 kilogram mass after the collision is 20 meters per seconds.
