How much tension must a rope withstand if it is used to accelerate a 6526 kg car vertically upwards at 8.9 m/s^2?
Answers
Answer:
The value is [tex]T = 122036.2 \ N[/tex]
Explanation:
From the question we are told that
The mass of the car is [tex]m = 6526 \ kg[/tex]
The acceleration is [tex]a= 8.9 \ m/s^2[/tex]
Generally the net force applied on the rope is mathematically represented as
[tex]F_{net} = T - W[/tex]
Here W is the weight of the car which is evaluated as
[tex]W = m * g[/tex]
=> [tex]W = 6526 * 9.8[/tex]
=> [tex]W = 63954.8 \ N[/tex]
Generally the net force can also be mathematically represented as
[tex]F = m * a[/tex]
So
[tex]m * a = T - 63954.8[/tex]
=> [tex]6526 * 8.9 = T - 63954.8[/tex]
=> [tex]T = 122036.2 \ N[/tex]
The rate of acceleration for a basketball that is falling to the ground is 9.8 meters per second. The force exerted on the basketball is 29.4 Newtons. What is the mass of the object?
Answers
Where mass is one kilogram
acceleration is one meter/second/second
m=f/a. Solve for the unknown (mass)
m= 29.4/9.8

i need help on this question.
Answers
Answer:
Answer: B. 49 N
Explanation:
Friction Force
When an object is at rest on a rough surface, it encounters a friction force that opposes motion.
The friction force when an object is moving on a horizontal surface is calculated by:
[tex]Fr=\mu_k N[/tex]
Where [tex]\mu_k[/tex] is the coefficient of static friction and N is the normal force.
If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal are equal in magnitude:
N = W = m.g
Thus, the friction force is:
[tex]Fr=\mu_k W[/tex]
We are given the coefficient of static friction [tex]\mu_k=0.5[/tex] and the mass of the object m=10 Kg. The minimum force needed to make it start moving is the maximum friction force:
Fr=0.5*10*9.8
Fr = 49 N
Answer: B. 49 N

A student thinks that any real vibration must be damped. Is the student correct? If so, give convincing reasoning. If not, give an example of a real vibration that keeps constant amplitude forever if the system is isolated.
Answers
Answer:
Yes the student is correct
Explanation:
The first law of thermodynamics states that energy can neither be created nor destroyed
The second law of thermodynamics states that the entropy (disorderliness) of an isolated system always increases
Therefore, whereby energy is not supplied to maintain the orderly oscillatory motion with constant amplitude, the amplitude of the system is bound to reduce with time that is the vibration of the system must be damped
what is friction. what are the two important properties of friction
Answers
Answer: 1. It always acts in the direction opposite to the direction of motion. 2. It's magnitude is equal to that of the force trying to set the object in motion only until it starts to move.
Explanation: Properties of frictional forces:
1. Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. 2. Frictional forces are caused due to intermolecular interactions between the bodies.
Explanation:
force is a force between two surfaces that are sibling
1. it acts parrell
2. it is caused due to intermolecular interactions between two bodies

A professional baseball player can throw the ball around 45 m/s if the distance between the pitcher and the batter is 18.39 m. How much time does it take for the ball to get to the batter?
Answers
Answer:
The time taken for the ball to get to the batter is 0.41 s.
Explanation:
Given;
initial velocity of the baseball, u = 45 m/s
horizontal distance between the pitcher and the batter, X = 18.39 m
The horizontal distance or range of a projectile is given as;
X = ut
where;
t is the time of flight
u is the initial velocity
t = X / u
t = 18.39 / 45
t = 0.41 s
Therefore, the time taken for the ball to get to the batter is 0.41 s.

How to find pressure when mass and area is given?
Answers
Answer:
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second units are newtons per square meter, or N/m2.
Explanation:
Do you not feel the pressure when mass is on you?
