A wheel of 0.5 m radius rolls without slipping on a horizontal surface. The axle of the wheel advances at constant velocity, mov

neonofarm [45]

Answer:

$\omega = 8\,\frac{rad}{s}$

Step-by-step explanation:

The translation speed of the wheel is:

$v=\frac{20\,m}{5\,s}$

$v=4\,\frac{m}{s}$

The angular speed of the wheel is:

$\omega = \frac{4\,\frac{m}{s} }{0.5\,m}$

$\omega = 8\,\frac{rad}{s}$

What is the Y- intercept of the graph of the line given by equation 3y+4x=15?

KATRIN_1 [288]

Yint is where the line crosses the y axis or where x=0
set x=0

3y+4x=15
x=0
3y+4(0)=15
3y+0=15
3y=15
divide by 3
y=5

yint is (0,5) or at y=5

Which function represents the number of seconds, s, in d days? (Hint: The number seconds in a day is 24 × 60 × 60 = 86,400.)

vaieri [72.5K]

<em>f(d)=86,400·d</em>
if you set 1 day (d=1) you get f(1)=86,400 sec
if you set 1 day (d=2) you get f(2)=172,800 sec
...etc.
