How much force would you need to accelerate a 4 kg object from a standstill to 5 m/s2?

Physics
1 answer:
djyliett [7]2 years ago
3 0

To solve this, we use Newtons 2nd law of motion which states that F = m⋅a . This means that a force F is required to make a body of mass m accelerate with an acceleration of a . So if a body of 4kg is to be accelerated by a force 17N then its acceleration can be found by putting into the formula F = m⋅a .

topjm [15]

Answer:

350J

Explanation:

Given parameters:

Weight of bag  = 20N

Distance moved horizontally  = 35m

Force applied  = 10N

Unknown:

Work done on the bag  = ?

Solution:

Work done is the force applied to move a body through given distance.

  Work done  = Force applied x distance

So;

 Work done  = 10 x 35  = 350J

A capacitor is connected to an AC generator. As the generator's frequency is increased, what happens to the current in the capac
Licemer1 [7]

Answer:

The current increases.

Explanation:

A capacitor can be defined as an electronic component used in electrical circuits to store charge temporarily.

A capacitor is connected to an AC generator. As the generator's frequency is increased, the current in the capacitor increases as well.

This ultimately implies that, when a capacitor is connected to an AC generator, the frequency of the circuit is directly proportional to the amount of current flowing through it.

How can you decrease the momentum of an object?
mamaluj [8]
You will have to "put force against the object to slow it down." Momentum is the force that is keeping a object moving in a certain direction so if you would want to slow down the object you will have to put another force against the object to slow it down or stop it. For example: a person kicks a ball, the ball moving is the momentum. So, if you would want to stop the ball you would have t put something in its path to slow it down which is the decreasing of it's momentum. Therefore you would put a bump in the wall and when the ball hits the bump it slows down.

Hope this helps!
