Question

An object has an x–momentum of 8.5 kilogram·meters/second and a y–momentum of 9.8 kilogram·meters/second. What is resultant momentum of the object?

Answer 1

The real answer is 12.97 kiligram m/s

Step-by-step explanation:

I just took the test.

Answer 2

Just use the pythagorean theorem.

sqrt(8.5^2 + 8.9^2) = resultant.
sqrt(72.25 + 79.21) = resultant
sqrt(151.46) = resultant
12.31 is the resultant momentum.
