Question 421763: mr. bloop is rolling small steal disks down a ramp. each disk is 4cm in diameter and 5mm thick. it takes 7 seconds to go down the ramp and the distance traveled from the top to the bottom of the ramp is 119cm. how many revolutions does a disk make on the way down? round your answer to the nearest hundreath. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! C=2πr
C=2π(2)=4π
Revolutions=119/4π=18.93 revolutions
The thickness of the disk and the time it takes to go down the ramp are irrelevant.
