To find: the distance moved by the wheel in 20 rotations.
Answer to Problem 14MCQ
The distance moved by the wheel in 20 rotations is
Explanation of Solution
Given info:
The distance travelled by the wheel directly varies with the number of rotations that is the distance travelled by the wheel directly proportional to the number of rotations.
Consider the distance moved by the wheel when it has 8 rotations is
Consider the rotation of the wheel when
Consider the distance moved by thewheel when it has 20 rotations is
Consider the rotation of the wheel when
Consider the proportionality constant as
Formula used:
Show the relation between rotation of the wheel and corresponding distance travelled as follows:
Neglect
Calculation:
Find the distance travelled by the wheel
Hence, the distance travelled by the wheel in 20 rotations is
Conclusion:
Thus, the distance travelled by the wheel moves in 20 rotations is
