Memories
by matthew smith

I remember when I met you
the smile on your face,
Seems like a million years ago -
a different time and place

I remember when I kissed you
the warmth inside my heart,
I thought it'd last a lifetime
I swore we'd never part

I thought about the future
I started making plans,
Forever you'd be my woman
forever I'd be your man

We went together places
so that everyone could see,
The women that I want to share
the rest of my life with me

I told you that I loved you
I told you that I cared,
I told you if you were falling
just look back and I'd be there

I know I didn't have all the answers
sometimes I only guessed,
But, through it all I have to say
"I always tried my best"

I wasn't always perfect
I wasn't always right,
I know sometimes I wasn't
even worthy in your sight

I know I took for granted
the love you had to share,
All I ever wanted was
for you to know I cared

Our lives have changed directions
as sometimes lovers do,
Often time and change
and pave a path that's new

Sometimes I often wondered
just what lies ahead,
Sometimes I'd like to turn back time
and take back what I said

We've both gone different places
we've both gone different ways,
I know sometimes I let you down
when trouble came our way

I know sometimes I did things
you didn't comprehend,
But, through the years and all the tears
our memories will never end........

This is due today and I’m confused on this question

Answers

Answer: 5.4 kg

Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have

F = ma

where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).

Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.

m = F/a

m = (120)/(22.35) ≈ 5.4 kg

Hence, the eagle has a mass of approximately 5.4 kg."

5.369 you can round to
5.37 or
5.4 or just

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

A pitcher throws a 145 g baseball at a velocity of 30.00 m/s. How much kinetic energy does the ball have?

Answers

Final Answer:

65.25 J is the kinetic energy that the ball has.

Explanation:

M = 145g

(Reminder: kg must be used in this formula, thus we need to convert 145g to kg)

M = 145g x 1kg/1000g

(cross out g, then multiply 145 to 1kg)

M = 145kg/1000 = 0.145kg

M = 0.145 kg

V = 30.00 m/s

Solution:

KE = 1/2mv^2

KE = 1/2(0.145kg)(30.00m/s)^2

(Square first the velocity)

KE = 1/2(0.145kg)(900.00m^2/s^2)

KE = 1/2(130.5 kg*m^2/s^2)

KE = 65.25 kg*m^2/s^2

(Reminder: 1 kg*m^2/s^2 = 1 J)

KE = 65.25 J

Final Answer:

65.25 J is the kinetic energy that the ball has.

Answers

Answer:

Graph-

Explanation:

The graph best shows the velocity v of the clay ball from when it is dropped until it hits the ground is attached below.

What is velocity?

Velocity is the time rate of change of displacement. The displacement and velocity both are vector quantities. They represent magnitude and direction as well.

Irene drops a clay ball at time t=0. The ball stops when it hits the ground.

When the clay ball drops, only force acting is due to acceleration due to gravity.

The velocity of the clay ball decreases with the time.

Thus, the graph best shows the velocity v of the clay ball from when it is dropped until it hits the ground is attached.
