Kevin and Kisha are ice skating. Kisha has a mass of 60 kg, and Kevin has a mass of 45 kg. As they face each
other, Kevin pushes off Kisha with a force of 54 N. Assume the friction between the skaters and the ice is
negligible.
t
Determine the magnitude of Kevin's acceleration.
Write your answer to two significant figures.
m/s
m
Answers
If Kevin with mass 45kg pushes Kisha with a force of 54N, the magnitude of Kevin's acceleration is 1.2 m/s²
Kisha's mass = 60 kg
Kevin's mass = 45 kg
Kevin pushes off Kisha with a force of 54 N
Since it was Kevin that pushed Kisha, and the required force is 54N, we can look for Kevin's acceleration using the equation below
F = ma
The considered mass is Kevin's mass
54 = 45a
a = 54/45
a = 1.2 m/s²
The magnitude of Kevin's acceleration is 1.2 m/s²

A cart of weight 20 N is accelerated across a level surface at 0.15 m/s?. What net force acts on
the wagon?
Answers
The net force that acts on the cart of wagon is calculated as 3N
HOW TO CALCULATE NET FORCE:
The net force of a body can be calculated by multiplying the mass of the body by its acceleration. That is;Force (N) = weight (N) × acceleration (m/s²)According to this question, a weight of 20N accelerated across a level surface at 0.15 m/s². The net force can be calculated as follows:F = 20 × 0.15
F = 3N
Therefore, the net force that acts on the cart of wagon is calculated as 3N.Learn more at: https://brainly.com/question/18109210?referrer=searchResults

If the mass of an object is 100 and Net force is 400, what would be the Acceleration?
And explain.
Answers
Answer:
[tex]4m/s^{2}[/tex]
Explanation:
I'm assuming the units for force and mass are Newtons and kilograms, respectively.
Rearranging Newton's first law (F=m*a) to solve for acceleration:
F=m*a
[tex]a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}[/tex]
The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.

6. 43°N latitude, 79°W longitude ⇒Niagara Falls, New York
7. 25°N latitude, 80°W longitude ⇒ Miami, Florida
What is a longitude?The term Longitude has been refered as the horizontal lines that are the measurement east or west of the prime meridian. Longitude are the imaginary lines that divide the Earth. Longitudes are also called the meridians, which run from north to south pole to pole but they measure the distance east or west.
The hypothesis that the species diversity is greater at lower latitudes than higher latitudes because low-latitude habitats are older would be supported if speciation rates were: the same at high and low latitudes.
Species diversity can be defined as the number of species, present in an area or the ecosystem. More are the number of species, more diverse is the area is. The richness and functionality of an ecosystem is estimated through its diversity.
Therefore,longitudes are the horizontal lines which divide the Earth.
