Answer 1

Answer:

P1 = momentum before collision = .5 kg * .32 m/s = .16 kg-m/s

Momentum is conserved

P1 = P2 = V * (M + m) = .16 kg-m/sec

V = .16 kg-m/sec / (.5 kg + .3 kg) = .2 m/sec

An book fell from a shelf 1.5 meters from the ground. If it took the book 3 seconds to hit the ground, what was the velocity of the book?

Answers

The initial velocity of the book before its hits the ground is 14.2 m/s.

The given parameters;

height of the book above the ground, h = 1.5 mtime of motion of the book, t = 3 seconds

The initial velocity of the book is calculated as follows;

h = ut + ¹/₂gt²

where;

u is the velocity of the book

1.5 = 3u + (0.5 x 9.8 x 3²)

1.5 = 3u + 44.1

3u = 1.5 - 44.1

3u = -42.6

[tex]u = \frac{-42.6}{3} \\\\u = -14.2 \ m/s\\\\u = 14.2 \ m/s \ downwards[/tex]

Thus, the initial velocity of the book before its hits the ground is 14.2 m/s.

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.

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.

Why are occupants of the international space station weightless?

Answers

The astronauts, the ISS itself and other objects in Earth orbit aren't floating, they are actually falling. ... So, as they accelerate towards the Earth, the Earth curves away beneath them and they never get any closer. Since the astronauts have the same acceleration as the space station, they feel weightless.

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

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.
