During a very quick stop, a car decelerates at 7.00 m/s2 . (a) What is the angular acceleration of its 0.280-m-radius tires, ass

love history [14]

Answer:

-25 rad/s²

29 times

3.8 seconds

50.54 m

26.6 m/s

Explanation:

$\omega_f$ = Final angular velocity

$\omega_i$ = Initial angular velocity

$\alpha$ = Angular acceleration

$\theta$ = Angle of rotation

a = Acceleration = -7 m/s² (negative because of deceleration)

r = Radius of wheel = 0.28 m

Angular acceleration is given by

$\alpha=\frac{a}{r}\\\Rightarrow \alpha=\frac{-7}{0.28}\\\Rightarrow \alpha=-25\ rad/s^$

Angular acceleration of the wheel is -25 rad/s²

$\omega_f=\omega_i+\alpha t\\\Rightarrow t=\frac{\omega_f-\omega_i}{\alpha}\\\Rightarrow t=\frac{0-95}{-25}\\\Rightarrow t=3.8\ s$

It took 3.8 seconds for the car to stop

$\theta=\omega_it+\frac{1}{2}\alpha t^2\\\Rightarrow \theta=95\times 3.8+\frac{1}{2}\times -25\times 3.8^2\\\Rightarrow \theta=180.5\ rad$

$\frac{180.5}{2\pi}=28.72746\ rev$

The wheel rotated 29 times.

The

Initial velocity

$u=r\omega_i\\\Rightarrow u=0.28\times 95\\\Rightarrow u=26.6\ m/s$

The car’s initial velocity is 26.6 m/s

$s=ut+\frac{1}{2}at^2\\\Rightarrow s=26.6\times 3.8+\frac{1}{2}\times -7\times 3.8^2\\\Rightarrow s=50.54\ m$

Distance covered in the time is 50.54 m

If the distance is found in meters we get 50.54 m which is very low. Considering the initial velocity is 95.76 km/h. Coming to a stop in that distance is very low. So, the values do not seem reasonable. At least a 100 m is required to stop from that speed.

gavmur [86]

Answer:

Land Slides

Explanation:

The type of mass wasting that most likely would have occurred in the mountain valley near Durango, Colorado is land slide or land slump.

The heavy rain might have loosened the soil and the rock strata of the mountain valley.And this Loosened mud, rock would have slide down along the inclined slops of the mountain leading to land slides.
