The answer is A
7.152 is less than 7.512 so the greater than symbol would be facing 7.512
Radius = r = 1 foot
Angular velocity = w = 1 revolutions in 4 seconds
So,
w = 0.25 revolutions per second
Since,
1 revolution = 2π radians
We can write the above equation as:
w = 0.25 x 2π radians per second = 0.5π radians per second
Linear Velocity = v = r w
Using the values, we can write:
v = 1 x 0.5π
= 0.5 π
= π/2 feet per second
Therefore, the correct answer is option B
Answer: 1) equation relating both
N+F = 19
2)N = 7
Step-by-step explanation:
N+F =19
He folded 12, so F = 12
N = 19-12 = 7
I think it’s -1.69642857143
