Answer:

Speed

Explanation:

If a vehicle hit any other object then its speed will slow down or some time the vehicle will stop its depends on the force exerted by other object on the vehicle.

The change in speed of vehicle is due to momentum because momentum is always conserved. So to conserve the momentum the speed of the vehicle decreases because after hitting the overall mass is increases.

Beginning 145 miles directly south of the city of Hartville, a car travels due west. If the car is travelling at a speed of 42 m
ziro4ka [17]

Answer:

The rate of change of the distance is 14.89.

Explanation:

Given that,

Distance = 145 miles

Speed of car = 42 miles/hr

Distance covered by car = 55 miles

We need to calculate the the rate of change of the distance

According to figure,

Let OA is x, and AB is y.

Now, using Pythagorean theorem

x^2=y^2+145^2

On differentiating

2x\dfrac{dx}{dt}=2y\dfrac{dy}{dt}

\dfrac{dx}{dt}=\dfrac{y}{x}\dfrac{dy}{dt}

\dfrac{dx}{dt}=\dfrac{55\times42}{\sqrt{55^2+145^2}}

\dfrac{dx}{dt}=14.89\ miles/hr

Hence, The rate of change of the distance is 14.89.

The solid right-circular cylinder of mass 500 kg is set into torque-free motion with its symmetry axis initially aligned with th
aivan3 [116]

Answer:

30.95°

Explanation:

We need to define the moment of inertia of cylinder but in terms of mass, that equation say,

A=\frac{1}{12}m(3r^2+l^2)

Replacing the values we have,

A=\frac{1}{12}(500)(3(0.5)^2+(2)^2)A=197.9kg.m^2

At the same time we can calculate the mass moment of intertia of cylinder but in an axial way, that is,

c=\frac{1}{2}mr^2

c=\frac{1}{2}(500)(0.5)^2

c=62.5kg.m^2

Finally we need to find the required angle between the fixed line a-a (I attached an image )

\Phi = 2tan^{-1}\sqrt{\frac{(\frac{A}{cos\gamma})^2-A^2}{c^2}}

Replacing the values that we have,

\Phi = 2tan^{-1}\sqrt{\frac{(\frac{197.9}{cos5\°})^2-197.9^2}{62.5^2}}

\Phi = 2tan^{-1}(\sqrt{0.076634})

\Phi = 2tan^{-1}(0.2768)

\Phi = 2(15.47)

\Phi = 30.95\°
