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.
Answer:
Happy dagger
TImeless end
Explanation:
An oxymoron is a type of figure of speech that puts two contradictory ideas or words side by side.
A dagger is a weapon, and the word "happy" is a positive adjective and placing a weapon besides a word such as happy is an example of oxymoron.
Timeless means something that is unending, till infinity, something that has no conclusion.
The word "end" signifies the conclusion of something and putting the word "timeless" and "end" side by side is an oxymoron.
