How does inertia affect a person who is not wearing a seatbelt during a collision?

ELEN [110]2 years ago

A person who is not wearing a seatbelt during a collision will be thrown forward because it maintains forward motion

<h3>Further explanation </h3>

In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero,  it can be formulated :

\large{\boxed{\bold{\Sigma F = 0}}}

then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called<em> inertia </em>

The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.

In objects with mass m that move translatively, the object will maintain its linear velocity

When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.

<u><em>The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.</em></u>

Explanation:

The inertia of a body is a property contained by the body by virtue of its mass. Higher the mass of a body, higher will be the inertia.

According to the Newton's first law of motion i.e. law of Inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body to change its state.

When a car is moving on a road, the car is in motion and the body of the person in the car is also in the motion along with the car. Now if the car faces any collision, the car will suddenly come to rest.

But the body of the person sitting in the car continues to be in motion as there is no external force acting on the body. If the person is not wearing the seat-belt, the body moves forward and the person may hit the dashboard very hard.

The seat-belt stops the person's body to move ahead and hit the dashboard. So, the seat-belt prevents the person from injury by stopping the body.

Thus, <u><em>The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.</em></u>

A wheel has a rotational inertia of 16 kgm2. Over an interval of 2.0 s its angular velocity increases from 7.0 rad/s to 9.0 rad/
german

Answer:

<h2>128.61 Watts</h2>

Explanation:

Average power done by the torque is expressed as the ratio of the workdone by the toque to time.

Power = Workdone by torque/time

Workdone by the torque = \tau \theta = I\alpha * \theta

I is the rotational inertia = 16kgm²

\theta = angular\ displacement

\theta = 2 rev = 12.56 rad

\alpha \ is \ the\ angular\ acceleration

To get the angular acceleration, we will use the formula;

\alpha = \frac{\omega_f^2- \omega_i^2}{2\theta}

\alpha = \frac{9.0^2- 7.0^2}{2(12.54)}\\\alpha = 1.28\ rad/s^{2}

Workdone by the torque = 16 * 1.28 * 12.56

Workdone by the torque = 257.23 Joules

Average power done by the torque = Workdone by torque/time

=  257.23/2.0

= 128.61 Watts

Objects change motion due to forces. When they become unbalanced, their motion changes, while balanced forces cause constant mot
Neko [114]

Answer:

Balanced forces: When a number of forces acting on a body do not cause any change in its state of rest or of uniform motion along a straight line then the forces are said to be balanced forces. In other words, a body is said to be underbalanced forced when the resulting force acting on the body is zero.

The balanced forces:

⋅ Cannot set any stationary body into motion.

⋅ May change the shape and size of soft objects.

⋅ Cannot change the speed/velocity of a moving body.

Unbalanced forces:

When the resultant of all the forces acting on a body is not zero, then forces are called unbalanced forces.

Example:

⋅ Game of tug of war: When the forces exerted by both the teams are equal, then the rope does not move. But, if the force applied by team A is greater than team B, then the rope, as well as members of the weaker team, i.e., B, will be pulled towards A. The unbalanced force can (a) Set a stationary body in motion.

⋅ Set a moving body at rest.

⋅ Change the direction of motion.

Sunshine Corporation is expected to pay a dividend of $1.50 in the upcoming year. Dividends are expected to grow at the rate of
grigory [225]

Answer:

$25

Explanation:

The computation of the intrinsic value of the stock is shown below:

As we know that

Intrinsic value or Price = Dividend ÷ (Cost of equity - growth rate)

where,

Cost of equity or ke  is

= Risk free rate of return  + beta × (Market rate of return - risk free rate of return)

= 6% + 0.75 × (14% - 6%)

= 12 %

So the intrinsic value is

= $1.50 ÷ (12% - 6%)

= $25
