<u>Solution and Explanation:</u>
The following calculation is made in order to find out the area and the final velocity vector.
Using the given information and the data in the question,
m1u1 + m2u2 = (m1 + m2) multiply with v
40000 multiply with ( -20i ) + 60000 multiply with ( 10j ) = 100000 multiply with v
Therefore, v = -8i + 6j
That is |v| = 10 knots towards the 36.86 degree north of the west

Answer:
10,000 years
Explanation:
Given that,
Half life of the radioactive isotope,
= 5000 years
Initial composition,
= 16 grams
Final composition,
= 4 grams
We know that,

Therefore, the age of the rock is 10,000 years.
