If a group of workers can apply a force of 1000 newtons to move a crate 20.0 meters on a frictionless ramp: How high up a ramp will the crate travel?

Answers

Answer 1

Answer: That's going to depend on the mass of the crate. They'll be able to push a crate full of pingpong balls really high, but they may not be able to even budge the crate at all if it's full of bricks.

How to find the time in the air based off of the height and velocity

Answers

Answer:

To find time to reach maximum height given initial velocity use the equation Vf=vi+at. At the maximum height, the object has no initial velocity left and therefore you can substitute 0 for the Vf in the equation.

a lump of putty and a rubber ball have equal mass. both are thrown with equal speed against a wall. the putty sticks to the wall. the ball bounces back at nearly the same speed with which it hit the wall. which object experiences the greater momentum change?

Answers

The bouncy ball experiences the greater momentum change.

To understand why, you need to remember that momentum is actually
a vector quantity ... it has a size AND it has a direction too.

The putty and the ball have the same mass, and you throw them
with the same speed. So, on the way from your hand to the wall,
they both have the same momentum.
Call it " M in the direction toward the wall ".

After they both hit the wall:

-- The putty has zero momentum.
Its momentum changed by an amount of M .

-- The ball has momentum of " M in the direction away from the wall ".
Its momentum changed by an amount of 2M .

Rubber ball will experience the greater momentum change than the lump of putty

$\texttt{ }$

Further explanation

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

$\large {\boxed {F = ma }$

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem !

$\texttt{ }$

Given:

mass of a lump of putty = m

mass of rubber ball = m

initial speed of putty = v

final speed of putty = 0

initial speed of rubber ball = v

final speed of rubber ball = -v

Asked:

the change in momentum = Δp = ?

Solution:

Lump of Putty :

$\Delta p_(putty) = mv_f' - mv_i$

$\Delta p_(putty) = m(0) - mv$

$\Delta p_(putty) = - mv$

$\texttt{ }$

Rubber Ball:

$\Delta p_(ball) = mv_f' - mv_i$

$\Delta p_(ball) = m(-v) - mv$

$\Delta p_(ball) = - 2mv$

$\texttt{ }$

$\Delta p_(ball) : \Delta p_(putty) = - 2mv : - mv$

$\Delta p_(ball) : \Delta p_(putty) = 2 : 1$

$\Delta p_(ball) = 2\Delta p_(putty)$

$\Delta p_(ball) > \Delta p_(putty)$

From calculation above , we can conclude that rubber ball will experience the greater momentum change than the lump of putty

An ____________ is a circuit board that can be attached to the motherboard to add features such as video display and audio capability to the computer

Answers

Final Answer:

An expansion card is a circuit board that can be attached to the motherboard to add features such as video display and audio capability to the computer.

Explanation:

An expansion card, also known as an add-in card or expansion board, is a hardware component designed to enhance a computer's capabilities by providing additional functionality. These cards can be attached to the motherboard of a computer to add various features or capabilities, including video display and audio processing.

Expansion cards come in various forms and serve different purposes. For example, a graphics card is a type of expansion card that is commonly used to improve a computer's graphics performance. It can handle complex graphical tasks, making it essential for gaming, video editing, and graphic design. Another common type is the sound card, which enhances a computer's audio capabilities, enabling high-quality sound output and input for tasks like music production and gaming.

The process of adding an expansion card involves inserting it into a compatible slot on the motherboard, securing it in place, and installing the necessary drivers and software to ensure proper functionality. Most motherboards have multiple slots to accommodate various types of expansion cards, allowing users to customize their computer's capabilities based on their specific needs.

In summary, expansion cards are crucial components that enable users to expand and upgrade their computer's capabilities, whether it's for gaming, multimedia, or other specialized tasks.
