How much work is required to increase the kinetic energy of a car by 5000 J?
Work required to increase the kinetic energy.
Answer to Problem 41A
Explanation of Solution
Given:
The increase in kinetic energy is,
Formula Used:
The work required is equal to the change in kinetic energy, that is
Work = ? KE
Calculation:
As work done is equal to the increase in kinetic energy and change in kinetic energy is
So, work required is
Conclusion:
Therefore, the work required is
