what is the momentum of a 20-kg dog running at a speed of 8 m/s
The momentum of a 20-kg dog running at a speed of 8 m/s is 160 kg.m/s. This is calculated using the formula for momentum, which is the product of mass and velocity.
Explanation:To calculate the momentum of an object, you need to multiply its mass by its velocity. This is due to the fact that momentum is directly proportional to the object's mass and its velocity. Hence, a 20-kg dog running at a speed of 8 m/s would have a momentum of 160 kg.m/s.
Momentum (p) is represented as the product of mass (m) and velocity (v), hence expressed as p = m*v. Momentum is a vector quantity, which means it has both magnitude (amount) and direction. In this case, we're only concerned with its magnitude.
So, for the 20-kg dog running at 8 m/s, we substitute these values into the momentum formula to find its momentum:
p = m*vp = 20kg * 8 m/sp = 160 kg.m/sLearn more about Momentum here:https://brainly.com/question/30677308

a table is 6 feet long and 3 feet wide. You extend the table by inserting two identical table leaves. The longest side length of each rectangular leaf is 3 feet. The extended table is rectangular with an area of (18+6x) square feet. a) write an algebraic expression that represents the length of the extended table b) what does your variable represent?
a. The algebraic expression that represents the length of the extended table is 6 + 2x
b. The variable 'x' represents the length added by inserting each identical table leaf.
How to write an algebraic expression
a) To write an algebraic expression representing the length of the extended table, consider the original length of the table (6 feet) and the length added by inserting two identical table leaves (each with a longest side length of 3 feet).
Let's denote the length added by inserting the table leaves as 'x'.
Since we're inserting two identical leaves, the total length added would be 2x.
The length of the extended table can be expressed as the sum of the original length (6 feet) and the length added by the table leaves (2x):
Length of the extended table = 6 + 2x
b) The variable 'x' represents the length added by inserting each identical table leaf. It quantifies the extra length that extends the original table when the leaves are inserted.

A hiker is walking down a mountain. She walked 5,978 feet in 17 minutes. In that time, she descended 1,024 feet from the top of the mountain. She then walked 3,972 feet in 7 minutes. In that time, she descended 500 more feet. Express the average rate of change in altitude of the hiker from her starting point to her ending point as a unit rate.
The average rate of change in altitude of the hiker from her starting point to her ending point is -63.5 feet per minute.
The following can be deduced based on the information provided in the question:
During the first walk, she descended 1024 feet and during the second walk, she descended 500 feet. Therefore, the total will be:
= 1024 feet + 500 feet = 1524 feet
During the first walk, the time taken was 17 minutes while for the second walk, the time taken was 7 minutes. Therefore, the total time taken will be:
= 17 minutes + 7 minutes
= 24 minutes.
Therefore, the average rate will be:
= 1524 / 24
= 63.5 feet per minute

1.)In two or more complete sentences, explain how to find the time it takes for a rocket following the path, h(x) = -4x 2 + 16x, to hit the ground.
2.)A ball is thrown straight up from the top of a building that is 280ft high with an initial velocity of 48ft/s. The height of the object can be modeled by the equation s(t) = -16t 2 + 48t + 280.
In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.
1.) You plug a number into the variable x. Then you will solve the equation for h(x) to find the time it takes for the rocket to travel the path given.
Answer:
Step-by-step explanation:
Given that a rocket path is given by
[tex]h(x) = -4x^2 + 16x[/tex]
When it hits the ground h(x) =0
Hence we get
[tex]-4x^2 + 16x=0\\x=0, 4[/tex]
i.e. after 4 minutes the rocket hits the ground
2) Given that
[tex]s(t) = -16t^2 + 48t + 280.[/tex]
We have to find time t when height >280
[tex]s(t) = -16t^2 + 48t + 280>280\\\\t=0, 3[/tex]
Between 0 and 3 seconds the object would be above the building.

What is the acceleration of a wagon of mass 20 kg if a horizontal force of 64 N is applied to it? (Ignore friction)
The acceleration of the wagon is 3.2 m/s².
Explanation:To find the acceleration of the wagon, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force applied to it divided by its mass. In this case, the net force is 64 N (the horizontal force applied) and the mass of the wagon is 20 kg. So the acceleration can be calculated as follows:
A = F/M = 64 N / 20 kg = 3.2 m/s²
Therefore, the acceleration of the wagon is 3.2 m/s².
