You get 3x + 4x, +4- -3,and +3 + 4
Since GL and HI are parallel to each other, then in the translation this condition is going to be kept. So that, we can write in these gaps that AB and FE are parallel to each other.
D divide by 1000… you are shifting the decimal 3 places (there are 3 zeros in 1000) you are dividing because the number is getting smaller.
First, we want to convert 600 feet to inches:
600 feet (12 inches/ft) = 7200 inches
We know that the diameter is 60 inches, so the circumference is 60π inches or 188.5 inches.
We can divide 7200/188.5 to get about 38.2 rotations.
The angular velocity is the linear speed divided by the radius.
ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
ω = 45 degrees/second
