The answer to your question would be C
Saturn is the second largest planet in our solar system. At an average distance of 800 million miles (1.3 billion kilometers) from Earth, Saturn is the farthest planet that can be seen without a telescope. Saturn is the sixth planet from the sun. Because Saturn is so far away from the sun, Saturn is considered one of the outer planets. Despite it's large size, Saturn is the least dense planet in our solar system!
Answer:
2.22m/s
Explanation:
Given parameters:
M1 = 60kg
M2 = 75kg
V1 = 0m/s
V2 = 4m/s
Unknown;
Velocity after collision = ?
Solution:
To solve this problem, we must understand that the momentum before and after collision of the bodies must be the same;
M1 V1 + M2 V2 = v(M1 + M2)
So;
60 x 0 + 75 x 4 = v (60 +75)
300 = 135v
v = 2.22m/s
