The increase in the kinetic energy of a sprinter if its velocity increases by three times.
Answer to Problem 37A
Kinetic energy increases by
Explanation of Solution
Given:
The final velocity is
Formula used:
The kinetic energy of an object of mass
Calculation:
Let the initial velocity and the kinetic energy be,
Then, the final kinetic energy of the sprinter will be,
Conclusion:
Thus, the sprinter’s kinetic energy will become
