A car is moving at 80km/h accelerates to pass a truck. Five seconds later the car is moving at 100km/h. What is the Acceleration of the car? Please show the equation, Ty.
Answer/Explanation:
Acceleration is the rate of change of the velocity of an object that is moving. This value is a result of all the forces that is acting on an object which is described by Newton's second law of motion. Calculation of such is straightforward, if we are given the final velocity, the initial velocity and the total time interval. We can just use the kinematic equations. Fortunately, we are given these values. So, we calculate as follows:
acceleration = v - v0 / t
acceleration = (80 mph - 50 mph) ( 1 h / 3600) / 5 s
acceleration = 1.67 x 10^-3 m / s^2

Which spring has more potential energy stored?
a) 1.0 N/m constant spring stretched 0.2 m.
b) 2.0 N/m constant spring stretched 0.2 m.
c) 1.0 N/m constant spring stretched 0.3 m.
d) 2.0 N/m constant spring stretched 0.3 m.
Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
Answer: c) 1.0 N/m constant spring stretched 0.3 m.

Answer:
When mass is greater, the force needed must be greater keeping the acceleration of the wheel chair constant
Explanation:
[tex]force = mass \times acceleration \\ f \: \alpha \: m[/tex]

Speed, Velocity, & Acceleration PUZZLE
Answer:
The way to solve the puzzle is given below.
Explanation:
Speed: The rate of change in distance covered by the body.
Velocity: The speed of the body having direction.
Acceleration: The rate of change of velocity.
Now,
According to the question we have to fill the blank triangles in the larger triangle.
Step by step:Draw the bigger triangle first with all the markings on it.Now, let us start with the upper left triangle. in that, we are given two labelings and we have to match them with their corresponding.As we know unit for acceleration is m/s². So, write it to the corresponding line.Similarly go for the next one.Match all the statements with their corresponding statement then fill the leftover spaces using the smaller triangle statement which matches them appropriately.Hence we get the required triangle.Learn more about speed here:

An astronomer writes down the following for an object in the night sky: azimuth 364˚ and altitude 93˚, what is wrong with the values?
If your azimuth is larger than 180 degrees, multiplying it by 180 degrees to find your rear azimuth will result in an azimuth that is greater than 360 degrees.
What azimuth 364˚, altitude 93˚, what is wrong with values?A circle has 360 degrees, thus if your azimuth is higher than 180 degrees, multiplying it by 180 degrees to find your back azimuth will result in an azimuth higher than 360 degrees.
Because many ancient calendars had 360 days, it may be because the stars appeared to rotate around the north star at a rate of around 1 degree every day that azimuth is measured using a 0-360° interval. Azimuth is utilized outside of astronomy in disciplines like navigation and geology.
Therefore, Whereas an object at 90 degrees height is directly overhead, one at 0 degrees altitude is just above the horizon.

Which most likely has the greatest conductivity? a warm plastic rod a cool rubber tube a cool silver strip a warm copper wire
Answer:
Copper
Explanation:
Plastic and Rubber are both bad conductors of electricity so it cant be those
Copper is a good conducter of electricity since it warms up it allows electrons to move easily faster than silver.
A cool silver strip most likely has the greatest conductivity.
What is meant by conductivity ?The ability of a material to transmit heat or an electric charge through it is measured by its conductivity.
Here,
A conductor is a substance that offers extremely little resistance to the transmission of thermal or electrical energy.
Metals, semiconductors, and insulators are the three main categories of materials. The least conductive materials are called insulators which include ceramic, wood, and plastic, while metals are the most conductive materials.
Of all metals, silver has the highest electrical conductivity. In actuality, silver is the benchmark metal against which all other metals are measured for conductivity.
On a scale of 0 to 100, silver scores a perfect 100, followed by copper at 97 and gold at 76.
Hence,
A cool silver strip most likely has the greatest conductivity.

Explanation:
Given Data:
Mass = m = 50 kg
Height = h = 20 m
Acceleration due to gravity = g = 10 m/s²
Required:
Potential Energy = P.E. = ?
Formula:
P.E. = mgh
Solution:
P.E. = (50)(20)(10)
P.E. = 10,000 Joules
P.E. = 10 * 10³ Joules (10³ = Kilo)
