A 150 g egg is dropped from 3.0 meters. The egg is moving at 4.4 m/s right before it hits the ground. The egg comes to a stop in

0.072 seconds.
What is the magnitude of force that the ground exerted on the egg?

0.66 N

9.2 N

13 N

180 N

Answer is 9.2 N

Answer: Magnitude of the force exerted on the egg by the ground is 9.2N

Explanation:

Given the following :

Mass of egg (m) = 150g = 0.15kg

Height(h) from which egg is dropped = 3m

velocity of egg before hitting the ground (u) = 4.4m/s

Final velocity of egg (V) = 0

Time taken (t) = 0.072s

Magnitude of the force exerted on the egg by the ground can be found by applying Newton's 2nd law:

Momentum = mass × velocity

From Newton's second law:

Force = mass × change in Velocity with time ;

That is

F = m * ΔV / t

Inputting our values

F = 0.15 * (4.4 - 0) / 0.072

F = 0.15 × (4.4 / 0.072)

F = 0.15 × 61.11

F = 9.16N

F = 9.2N

What is the ball's acceleration?
muminat

Answer:

g, downward

Explanation:

It is given that, a baseball is thrown straight upward. The force acting on the stone is force of gravity. It is moving under the action of gravity. We know that the force of gravity always acts in a downward direction.

At the highest point, the velocity of the stone will be equal to 0. It will move will constant acceleration equal to g and it always acts in downward direction.

Hence, the correct option is (e) "downward direction".

Pure water has a hydrogen ion concentration of 1 x 10 (-7) M and a ph of 7. A student measures a basic solution and finds that i
Lena [83]

The student must have made an error in her measurement in the concentration of hydrogen ion in the basic solution given. From her measurement, the concentration is  1 × 10−3 M. If we calculate the pH, we get:

pH = -log ( 1 × 10−3) = 3

A pH of 3 does not signifies a basic solution it is in the acidic range. So, the measurement is wrong.

A pipe originally has a radius of 1.25m. It narrows down to a radius of 0.55m. If the original force in the big pipe is 72N, wha
Gemiola [76]

Use direct proportionality: If 1.25 m = 72 N, then 0.55 m = y

0.55 m × 72 = 39.6.

39.6÷1,25 gives you your answer which is 31.68 N.

Which factors affect the speed of sound? type and volume of medium temperature and type of medium volume and temperature of medi
rusak2 [61]
<h3><u>Answer;</u></h3>

temperature and type of medium

<h3><u>Explanation;</u></h3>
  • <em><u>The speed of sound depends on the elasticity and density of the medium through which it is traveling</u></em>. That is sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
  • <em><u>The speed of sound also depends on temperature.</u></em> Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.
