Answer:
The linear speed of the bike is 19.242 miles per hour.
Step-by-step explanation:
If sliding between the bottom of the wheel and ground can be neglected, the motion of the wheel can be well described by rolling, which is a superposition of coplanar pure rotation and translation, The speed of the bike occurs at the center of the wheel, where resulting instantaneous motion is pure translation parallel to ground orientation. The magnitude of the speed of bike (
), measured in inches per second, is:
Where:
- Radius, measured in inches.
- Angular speed, measured in radians per second.
Now, the angular speed must be converted from revolutions per minute into radians per second:
The speed of the bike is: (
and )
Lastly, the outcome is converted into miles per hour:
The linear speed of the bike is 19.242 miles per hour.
Even bc it doesn’t go through the origin
Answer:
8.30%
Step-by-step explanation:
you look at .3, which is in the tenths place. then you look to the left, if the number is 5 or higher, you round the 3 up, but if the number's lower, you erase all the numbers to the left of the place you want to round at
Answer:D hope it helped
Step-by-step explanation:
Answer:
The answer is A. the opposite of eight.
Step-by-step explanation:
The opposite of 8 is -8, and to prove this, the opposite of -8 is 8. This is correct.
The absolute value of 8 is 8, and the absolute value of any number (positive or negative) will always be positive, so this is incorrect.
8 above 0 means positive 8, so this is incorrect.
The opposite of -8 is positive 8, so this is incorrect.
I hope this helped! :-)
