URGENT: If there is a 2 kg ball and a 5 kg ball with the same kinetic
energy, which one will be moving faster?
a. the 5 kg ball
b. the 2 kg ball
C. They will move with the same speed
d. None of the above. Explain.
Answers
Answer:
there is less mass to move so the 2kg ball will move faster. the kinetic energy of the 5kg ball will move slower due to the fact that it needs more energy to move if it has more mass.
Answer:
the 2kg ball
Explanation:
there is less mass to move so the 2kg ball will move faster. the kinetic energy of the 5kg ball will move slower due to the fact that it needs more energy to move if it has more mass.

A net force of 40 N south acts on an object with a mass of 20 kg. What is the
object's acceleration?
(Hint: Use the formula a = f/m
A. a = 4 m/s 2 north
B. a = 2 m/s2 south
C. a = 10 m/s2 south
D. a = 20 m/s 2 north
Answers
Answer:
B. 2m/s² south
Explanation:
Given parameters:
Net force = 40N
Mass = 20kg
Unknown:
Acceleration of the object = ?
Solution:
To solve this problem, we use;
F = ma
F is the net force
m is the mass
a is the acceleration
a = [tex]\frac{f}{m}[/tex]
a = [tex]\frac{40}{20}[/tex] = 2m/s²
The acceleration of the object is 2m/s² south
What happens to the energy when the material is changed?
Answers
Answer: When a material is heated or cooled, two changes may happen to the particles within the material: Chemical bonds between the particles may form, break or stretch. There is a change in the chemical potential store of energy in the material. The material will heat up or cool down as the particles within it gain or lose speed.

Stephanie is in volleyball practices and she notices something interesting about the
effect that spiking the ball has on her hand. She notices that the harder she hits the
ball, the more that her hand hurts afterward. Which Newton's Law explains why this
happens?
Answers
The Newton's law that explains the reason for the pain experienced by Stephanie when she spikes the ball is Newton's third law of motion.
Newton's third law of motion, states that, action and reaction are equal and opposite.
The force exerted on the ball when Stephanie spikes is equal to the reaction the ball exerts back on Stephanie. As the force Stephanie applied increases, the reaction she receive from the ball increases as well and the more pain she will feel.
Thus, we can conclude that, the Newton's law that explains the reason for the pain experienced by Stephanie when she spikes the ball is Newton's third law of motion.

Which is a possible result of rising ocean temperatures caused by global warming?
formation of dust bowls
increase in strength of hurricanes
rapid evaporation of water in soil
decrease in population due to health threats
Answers
Answer:
Increase in strength of hurricanes
Explanation:
A possible result of rising ocean temperatures caused by global warming is an increase in the strength of hurricanes, which is the second option. As the ocean temperatures increase, more energy is available to fuel hurricanes, making them stronger and potentially more destructive.
What is global warming?Global warming is causing the earth's climate to change, which is having a significant impact on the world's oceans. As the temperature of the oceans increases, a variety of effects can occur. One of the most well-documented impacts is the increase in the strength of hurricanes. Hurricanes form over warm ocean waters, and as the water temperature rises, it provides more energy to the storm, making it more powerful.
Hence, a possible result of rising ocean temperatures caused by global warming is an increase in the strength of hurricanes, which is the second option.

If the force of gravity acting on the box is 88 N, what is the normal force acting on the box?
Answers
Answer:
88N
Explanation:
If the force of gravity acting on the box is 88N, then the normal force on the box is also 88N;
The force of gravity is the vertical pull of gravity on a body.
The normal force is the force a surface impresses on an object to prevent it from passing through.The normal force is equal to the gravitational force pull on a body.
So the solution is 88N

A motorcycle engine provides 473.3 N of force for 11.9 seconds. If the rider and the cycle have a mass of 2,068.3 kg, determine the change in velocity.
Answers
Answer:
After 11.9 seconds, the velocity will increase by approximately 2.7 m/s
Explanation:
Ignoring friction, we can simply say that the speed will increase by
11.9s × 473.3N / 2068.3kg
Which can be expressed as:
11.9s × 473.3kg·m/s² ÷ 2068kg
= (11.9 × 473.3 ÷ 2048.3) (kg·m/s² × s ÷ kg)
≈ 2.7 m/s

A block attached to a spring with an unknown spring constant oscillates with a period of 2.0 s. What is the period if
Answers
Answer:
a) If the mass is doubled, then the period is increased by [tex]\sqrt{2}[/tex]. Hence, the period of the system is 2.828 seconds.
b) If the mass is halved, then the period is reduced by [tex]\frac{\sqrt{2}}{2}[/tex]. Hence, the period of the system is 1.414 seconds.
c) The period of the system does not depend on amplitude. Hence, the period of the system is 2 seconds.
d) If the spring constant is doubled, then the period is reduced by [tex]\frac{\sqrt{2}}{2}[/tex]. Hence, the period of the system is 1.414 seconds.
Explanation:
The statement is incomplete. We proceed to present the complete statement: A block attached to a spring with unknown spring constant oscillates with a period of 2.00 s. What is the period if a. The mass is doubled? b. The mass is halved? c. The amplitude is doubled? d. The spring constant is doubled?
We have a block-spring system, whose angular frequency ([tex]\omega[/tex]) is defined by the following formula:
[tex]\omega = \sqrt{\frac{k}{m} }[/tex] (1)
Where:
[tex]k[/tex] - Spring constant, measured in newtons per meter.
[tex]m[/tex] - Mass, measured in kilograms.
And the period ([tex]T[/tex]), measured in seconds, is determined by the following expression:
[tex]T = \frac{2\pi}{\omega}[/tex] (2)
By applying (1) in (2), we get the following formula:
[tex]T = 2\pi\cdot \sqrt{\frac{m}{k} }[/tex]
a) If the mass is doubled, then the period is increased by [tex]\sqrt{2}[/tex]. Hence, the period of the system is 2.828 seconds.
b) If the mass is halved, then the period is reduced by [tex]\frac{\sqrt{2}}{2}[/tex]. Hence, the period of the system is 1.414 seconds.
c) The period of the system does not depend on amplitude. Hence, the period of the system is 2 seconds.
d) If the spring constant is doubled, then the period is reduced by [tex]\frac{\sqrt{2}}{2}[/tex]. Hence, the period of the system is 1.414 seconds.
