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:
Whales are known for working together, often when hunting for food. Orcas use teamwork to herd fast-swimming fish into groups so they’re easier to catch. Sperm whales use a similar technique. Humpback whales work in teams of up to 20 whales using a method called bubble-net feeding to catch their prey.
