Answer:

72mph/sec

Explanation:

The car goes from 100mph to 316mph in three seconds. Meaning it increases its speed by (316 - 100)mph in three seconds. That is 216 mph increase in three seconds. So, we divide the speed increase by the amount of time the increase occurred over. We get:

216mph / 3sec = 72mph/sec, our final answer

Hope it made sense. I would appreciate Brainliest, but no worries.

A bicycle wheel has an initial angular velocity of 1.10 rad/s . Part A If its angular acceleration is constant and equal to 0.20

MA_775_DIABLO [31]

Let $\theta$ , $\omega$ , and $\alpha$ denote the angular displacement, velocity, and acceleration of the wheel, respectively.

(A) The wheel has angular velocity at time $t$ according to

$\omega=\omega_0+\alpha t$

so that after 2.50 s, the wheel will have attained an angular velocity of

$\omega=1.10\dfrac{\rm rad}{\rm s}+\left(0.200\dfrac{\rm rad}{\mathrm s^2}\right)(2.50\,\mathrm s)=\boxed{1.60\dfrac{\rm rad}{\rm s}}$

(B) The angular displacement of the wheel is given by

$\theta=\theta_0+\omega_0t+\dfrac\alpha2t^2\implies\Delta\theta=\omega_0t+\dfrac\alpha2t^2$

After 2.50 s, the wheel will have turned an angle $\Delta\theta$ equal to

$\Delta\theta=\left(1.10\dfrac{\rm rad}{\rm s}\right)(2.50\,\mathrm s)+\dfrac12\left(0.200\dfrac{\rm ram}{\mathrm s^2}\right)(2.50\,\mathrm s)^2=\boxed{3.38\,\mathrm{rad}}$

How is pressure related to the sharpness of a knife and its ability to cut?

Gnesinka [82]

Pressure has inverse relationship with area of an object. The smaller the area is, more pressure it exerts. Increasing the sharpness of knife(decreasing its area), increases the pressure on an object i.e ability to cut increases on increasing the sharpness.
Hope this helps.
