Wheel Rolling
Wheel of diamrtr 7cm&14cms r 1980cms apart,start rolling towards each other simultaneously?
in opposite direction..they meet after 10seconds and both of them have the same number of revolutions.
what is the speed of the wheels and which wheel is having a greter velocity?
nπ(7+14)=1980, Solution is: {n=((660)/(7π))}= {n=30. 012}
30. 012π7= 210. 08π= 659. 99cm distance traveled by 7cm wheel
((659.99)/(10))= 65. 999cm /s speed of 7cm wheel
30. 012π14= 420. 17π= 1320.0cm distance traveled by 14cm wheel
((1320)/(10))= 132cm /s speed of 14 cm wheel
