Answer:
v ’= - 1.76 10⁻⁴ m / s
Explanation:
We can solve this problem using momentum conservation. Defined a system formed by the patient, his blood and the platform in such a way that the forces are internal and the moment is conserved
initial instnate. Before pumping
p₀ = 0
final instant. Right after the heart pumping
p_f = m v + M v'
where m is the mass of blood and M the mass of the patient + the platform
p₀ = p_f
0 = m v + M v’
v ’= -
let's calculate
v ’= - 0.30
v ’= - 1.76 10⁻⁴ m / s
To develop this problem it is necessary to apply the concepts related to the angular resolution of a telescope as well as to the arc length.
The arc length can be defined as
Where
r= Radius
\theta = Angle
At the same time the angular resolution of a body is given under the proportion
Where
= Wavelength
D = Diameter
Our values are given as
Then the angle of separation of the two objects seen from the observer is of
Finally, using the proportion of the arc length, in which we have the radius and angle we can know the separation of the two objects by:
Impulse = Force * times and also Impulse = change in momentum.
Given that the mass does not change, change if momentum = mass * (final velocity - initial velocity)
Given that you know mass and initial velocity (which is the velicity before the cart hits the wall) you need the final velocity (which is the velocity after the cart hits the wall).
Answer: the velocity of the cart after it hits the wall.
Hearing aid: It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities
Wheelchair: Gives mobility to people that can't or have a hard time walking.
Glasses: Corrects vision
Medicine: is used to cure, halt, or prevent disease
The velocity of a car with a mass of 3.1 kg is equal to 6.22 m/s
<u>Given the following data:</u>
- Kinetic energy = 60 Joules
To calculate the velocity of the car:
Mathematically, kinetic energy is calculated by using the formula;
<u>Where:</u>
- K.E is the kinetic energy.
- M is the mass of an object.
- V is the velocity of an object.
Making V the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity, V = 6.22 m/s
