2.5 x 103 kilogram truck with rubber tires moves through a 120 meter radius turn on a dry asphalt surface.
a. Determine the force of friction acting on the truck's tires during the turn.
b. Calculate the maximum speed with which the truck could have made this turn.
Answer:
a. The friction force acting on the truck's tires during the turn, is approximately 20,875 N
b. The maximum velocity with which the truck could make the bend is approximately 31.654 m/s
Explanation:
The given parameters of the truck are;
The mass of the truck, m = 2.5 × 10³ kg
The tire material = Rubber
The radius of the turn the through which the truck moves = 120 meters
The material and condition of the surface = Dry asphalt
a. The coefficient of friction of rubber tires on dry asphalt, μ ≈ 0.85 (researchgate (internet source))
The weight of the truck, W = m × g
Where;
m = The mass of the truck = 2.5 × 10³ kg
g = The acceleration due to gravity = 9.8 m/s²
∴ W = 2.5 × 10³ kg × 9.8 m/s² = 24,500 N
The force of friction acting on the tires, [tex]F_f[/tex] = W × μ
∴ [tex]F_f[/tex] = 24,500 N × 0.85 ≈ 20,875 N
The friction force acting on the truck's tires during the turn, [tex]F_f[/tex] ≈ 20,875 N
b. The centrifugal force the truck observes while turning through the bend, 'F', is given as follows;
F = m·v²/r
Therefore, the maximum velocity with which the truck could make the bend, 'v', is given when fiction force, '[tex]F_f[/tex]', is equal to the centripetal force, F
When [tex]F_f[/tex] = F, we have;
W × μ = m·v²/r
∴ 20,875 N = 2.5 × 10³ kg × v²/(120 m)
∴ v² = 20,875 N × (120 m)/(2.5 × 10^3 kg) = 1002 m²/s²
v = √(1002 m²/s²) ≈ 31.654 m/s
The maximum velocity with which the truck could make the bend, v ≈ 31.654 m/s
According to this question;
The mass of the truck (m) = 2.5 × 10³ kgThe radius of the turn = 120mThe coefficient of friction of rubber tires on dry asphalt, μ ≈ 0.85QUESTION 1:
Weight of the truck (W) = m × gWhere;
m = mass of the truck = 2.5 × 10³ kgg = acceleration due to gravity = 9.8 m/s²W = 2.5 × 10³ kg × 9.8 m/s² = 24,500 NThe force of friction acting on the tires, = W × μ= 24,500 N × 0.85 ≈ 20,875 NThe force of friction acting on the truck's tires during the turn = 20,875 NQUESTION 2:
Centrifugal force of the truck can be calculated as follows: F = mv²/rHowever, force of friction (Ff) is equal to centripetal force (F). That is;W × μ = m·v²/r20,875N = 2.5 × 10³ kg × v²/(120 m)v² = 20,875 × 120/2.5 × 10³ = 1002 m²/s²v = √1002 = 31.654m/sThe maximum velocity with which the truck could make the turn = 31.654 m/s.Learn more about force of friction at: https://brainly.com/question/4230804?referrer=searchResults
two homogeneous bodies of the same volume
Answer:
No, it is not necessary for them to have same mass.
Explanation:
Let both bodies have a density d1 and d2 respectively.
Since their volumes are equal V1 = V2
we know that, https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%7D
Hence, d1 = and d2 =
Taking the ratio of densities,we get
This implies that unless the bodies have same densities, the mass of the two bodies will not be same.

What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm³
Answer:
Explanation:
Density = mass/volume
132g/(48.9 cm³) = 2.7 g/cm³
(27 g)/(3 cm³) = 9 g/cm³
512 g/(65 cm³) = 7.9 g/cm³

Sally's mass on Earth is 50 kg. What is her mass on the moon?
Answer:
Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:
does this help
Sally's mass on Moon is: C. 50 kg
Mass is a measure of the amount of matter that an object or a body is typically made up of. The standard unit of measurement for the mass of an object is kilograms (kg).
Regardless of the location of a person, an object at any given time, mass (amount of matter that they're made up of) is always the same i.e constant.
This ultimately implies that, whether you're on the Moon, space, planet Earth or any other place; your mass would always remain the same or constant.
In this scenario, Sally's mass on Earth is 50 kg. Thus, we can deduce that her mass on Moon would be 50 kg.

How do we know when an object is in static or dynamic equilibrium?
Answer:
First Condition of Equilibrium
Explanation:
This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.

State the Law of Electric Charges in your own words.
[tex] \\ [/tex]
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

The mass of water in the kettle is 0.50 kg. The specific heat capacity of water is 4200 J/kg °C. The initial temperature of the water is 100 °C. Calculate the average power output from the water in the kettle to the surroundings in 2 hours
Answer:
1.27 Mega watt approx
Explanation:
Given data
Mass= 0.5kg
c= 4200 J/kg °C
T1= 100°C
Time = 2 hours >>>> 7200 seconds
From the given data the water is already at the boiling point
Hence if continuous heat is being added the latent heat of vapourization will result, the latent heat of vaporization is about 2,260 kJ/kg
Q= mL
Q= 0.5*2,260
Q = 1130kJ
Power= Energy * Time
Power= 1130* 1130
Power= 1.27mega watt approx

calculate the extra pressure when you are 10 meters under water. (density of water = 1000 kg/m3, g = 9.8 N/kg). Give a value only
Answer:
[tex]2.03\times 10^5\ Pa[/tex]
Explanation:
We need to find the extra pressure when you are 10 meters under water. The net pressure on us is given by :
[tex]P=P_o+\rho gh\\\\P=1.05\times 10^5+1000\times 9.8\times 10\\\\P=2.03\times 10^5\ Pa[/tex]
So, [tex]2.03\times 10^5\ Pa[/tex] is exerted on us at 10 m under water.
What is the pressure of the water coming out the bottom of a water tower that is 50 m
high in the air. (Density of water (1000kg/m^3).
Answer:
49,000 Pa
49 kPa
Explanation:
P (pressure)= hρg, where h= height, ρ=density, and g= acceleration due to gravity.
50 m * 1000kg/m³ * 9.8 m/s²
=49,000 kg*m⁻¹s⁻² OR 49,000 Pa OR 49 kPa
