How is Newtons second law apply to the egg drop ?

Physics
1 answer:
kotykmax [81]3 years ago
3 0

Answer:

Newton's Second Law is applied because of the acceleration caused by natural forces as the egg is plummeting to the earth. And the amount of acceleration the egg has will be largely affected by the amount of force Mr. Baker uses to hurl the egg to the ground.

Explanation:

hope that helps

Sonja [21]
You would be in an editing mode when you can see a blinking insertion point on a field. In addition, in any word processing software, it would basically signify that you can already type on the document. Another name for the insertion point would be the I-beam as displayed on the screen.

8. In the billiard ball room at the basement of Memorial Union, two identical balls are traveling toward each other along a stra
mel-nik [20]

Answer:

- Ball 1 will move backward at 7.89 m/s

- Ball 2 will move forward at 4.67 m/s

Explanation:

In an elastic collision, both the total momentum and the total kinetic energy of the system are conserved.

The conservation of the momentum can be written as:

m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2

where

m_1 is the mass of ball 1

m_2 is the mass of ball 2

u_1 is the initial  velocity of ball 1

u_2 is the initial velocity of ball 2

v_1 is the final velocity of ball 1

v_2 is the final velocity of ball 2

The conservation of kinetic energy can be written as

\frac{1}{2}m_1 u_2^2 + \frac{1}{2}m_2 u_2^2 = \frac{1}{2}m_1 v_1^2 + \frac{1}{2}m_2 v_2^2

Working together the two equations, it is possible to find two expressions for the final velocities in terms of the initial velocities:

v_1=\frac{m_1 -m_2}{m_1 +m_2}u_1+\frac{2m_2}{m_1+m_2}u_2\\v_2=\frac{2m_1}{m_1+m_2}u_1 -\frac{m_1 -m_2}{m_1 +m_2}u_2

In this problem we have:

m_1 = m_2 = m since the mass of the two balls is identical

u_1=+4.67 m/s is the initial velocity of ball 1

u_2=-7.89 m/s is the initial velocity of ball 2

Substituting into the equations, we find the final velocities:

v_1=\frac{2m}{m+m}u_2=u_2 =-7.89 m/s\\v_2=\frac{2m}{m+m}u_1=u_1=+4.67 m/s

Therefore:

- Ball 1 will move backward at 7.89 m/s

- Ball 2 will move forward at 4.67 m/s

How much electrical energy is used by a 350 W television that is operating for
Igoryamba

Answer:

525,000J

Explanation:

Power = work/time

Given

Power = 350 watts

Time = 25 mins = 25 x 60 = 1500 secs

Therefore

350 = work/1500

Cross multiply

Work = 350 x 1500

Work = 525,000J
