If a 50 N force was applied to a really massive object as well as a tiny object, what can you say

Physics
1 answer:
frozen [14]3 years ago
6 0

Answer:

The tiny object's acceleration will be much greater.

Explanation:

Because of Newton's second law of motion, (which is F=ma or Force= Mass*acceleration), then if the force maintains the same (which in this case it does, because it says 50 N to both obejcts) and  one mass was much greater than the other, then the ould be less for the more massive object and much greater for the lighter object.

For example:  If 50 N were applied to a 500 kg object and a 50 kg object, then theformulas for each (respectively) are:

50 = 500*acceleration

and

50 = 50*acceleration

(Because of Newtons Second Law of Motion)

Then, solving for the equations, we get for equation 1:

Acceleration = .1 m/s^2

And for equation 2:

Accleration = 1 m/s^2

Thus, you can see that more massive objects (when applied he same amount of force as the smaller object) clearly have less accleration than the smaller objects.

Why is centrifugal force is a fake force?<br>​
mash [69]

Answer:

We say fictitious because the actual source of the centrifugal acceleration is somewhat indirect and the experience one has results from the unbalanced forces acting on the reference frame, not a force. Note, it is an acceleration not a force. For instance, imagine yourself on a swing.

The coefficient of kinetic friction between Gary's shoes and the wet kitchen floor is 0.09. If Gary has a mass of 65 kg, what is
mariarad [96]

Answer:

57 N

Explanation:

Draw a free body diagram.  There are three forces:

Weight force mg pulling down.

Normal force N pushing up.

Friction force F pushing horizontally.

Sum of the forces in the y direction:

∑F = ma

N − mg = 0

N = mg

Friction force is the product of normal force and coefficient of friction:

F = Nμ

F = mgμ

F = (65 kg) (9.8 m/s²) (0.09)

F = 57.3 N

Rounded, the friction force is 57 N.

Which chart correctly describes the properties of magnets and electromagnets?

I'm gonna take a long shot here and say C. This is just based on common sense, sense electromagnets happen when electricity goes around a copper coil, as far as I know.<span />

Light waves travel most slowly through a ____<br><br> A) gas<br> B) solid<br> C) liquid
WITCHER [35]

Answer:

Liquid

Explanation: It can't be gas because gases are all around us and we can still see light. For solids it can't even move through a solid. Ex: If you're in a solid dome made of rock you can't get any light through. Let me know if I'm right!

You are playing ice hockey with friends on a frozen pond. The hockey puck (mass 0.2 kg) is sliding on the ice at 10 m/s when it
chubhunter [2.5K]

Answer:

The mass of the hailstone is  m_2 = 0.05

Explanation:

From the question we are told that

    The mass of the hockey puck is m_1  = 0.2 \ kg

     The initial speed of the puck is u_1 =  10 \ m/s

      The final speed of the puck is  v_f  =  8 \ m/s

According to the principles of linear momentum

      m_1u_1 + m_2u_2 = (m_1 + m_2)v_f

At initial the velocity of the hailstone was zero so

       u_2 =  0 \ m/s

So  

     m_1 u_1 =  (m_1 + m_2 )v_f

substituting values

        0.2 *  10 =  (0.2 + m_2 )* 8

=>     2 =  (0.2 + m_2 )* 8

=>     0.25 = 0.2 + m_2

=>    m_2 = 0.05
