a.
The combined kinetic energy of K and A.
a.
Answer to Problem 44A
Explanation of Solution
Given:
The mass of K and A are same as,
Their combined speed,
Formula used:
The kinetic energy of an object of mass
Calculation:
Using the above formula, the combined kinetic energy of K and A is,
Using given values in above,
Conclusion:
Thus, the combined kinetic energy of K and A is
b.
The ratio of their combined mass to K’s mass.
b.
Answer to Problem 44A
Explanation of Solution
Given:
The mass of K and A are same as,
Their combined speed,
Calculation:
The combined mass of K and A is,
Then, the ratio of their combined mass with K’s mass is,
Conclusion:
Thus, the ratio of their combined mass with K’s mass is
c.
The ratio of the combined kinetic energy of K and A to K’s energy. And, then to explain how this ratio is related to their masses.
c.
Answer to Problem 44A
Explanation of Solution
Given:
The mass of K and A are same as,
Their combined speed,
Formula used:
The kinetic energy of an object of mass
Calculation:
Using the above formula, the combined kinetic energy of K and A is,
And, the kinetic energy of K is,
Then, the ratio of their combined kinetic energy to Katia’s kinetic energy will be,
Conclusion:
Thus, the the ratio of their combined kinetic energy to K’s kinetic energy is
