Help me out! Thanks! You guys have really helped me before.

Question 1
What does the law of inertia say about the velocity and acceleration of a body that is subject to no external influences?
a) The velocity slows to zero as the object decelerates.
b) The speed can change but the direction of the velocity remains constant. The acceleration is along the same line as the velocity.
c) The velocity does not change, and the acceleration is zero.
d) The speed remains constant, but the direction of the velocity can change. All acceleration is perpendicular to the velocity.

Question 2
A car accelerates from a velocity of 10 m/s to 40 m/s in 1 minute. What is the acceleration of the car in units of m/s/s?

Question 3
A multiple flash photo is taken of a ball, which is thrown in the air. Another flash photo is taken of the same ball on its way back down. If there is no air friction, the following best describes the two pictures.
a. The first photo looks the same as the second one flipped upside down.
b. The second photo has equally spaced distance intervals while the first does not.
c. The first photo looks the same as the second one.
d. The first photo has equally spaced distance intervals while the second does not.

Question 4
An object is released above the ground and falls freely. Which of the following statements is true?
1. The velocity is greater at the top than at the midpoint and greater at the midpoint than at a point near the bottom.
2. The velocity is greater at a point near the bottom than at the midpoint and greater at the midpoint than at the top.
3. The acceleration is greater at a point near the bottom than at the midpoint and greater at the midpoint than at the top.
4. The acceleration is constant throughout the fall.

a) I and III
b) II and III
c) II and IV
d) I and IV

Question 5
Describe how you could use a stopwatch and a meter stick to measure a moving object's speed.

a) Use the stopwatch to measure the time for the moving object to travel between two points. Then, use the meter stick to measure the distance between the points. Divide the distance by the time.
b) Use the stopwatch to measure the time for the moving object to travel between two points. Then, use the meter stick to measure the distance between the points. Subtract the time from the distance.
c) You cannot measure speed with a meter stick and a stopwatch.
d) Use the stopwatch to measure the time for the moving object to travel between two points. Then, use the meter stick to measure the distance between the points. Divide the time by the distance

I will be happy to critique your thinking or work.

I meant help give me links for help. Someone else on the site did that and helped me.

Now...I do guesswork and hope for the best.

thanks...........

I'm glad to hear that we've been helpful to you in the past! Unfortunately, as an AI text-based bot, I can't provide you with specific links, but I can certainly help explain how to find the answers to your questions.

Question 1:
The law of inertia, also known as Newton's first law of motion, states that an object at rest will stay at rest, and an object in motion will stay in motion with the same velocity and in the same direction, unless acted upon by an external force. To answer this question, you need to identify which option correctly describes the velocity and acceleration of a body that is subject to no external influences. Read through each option carefully and determine which one aligns with the law of inertia.

Question 2:
Acceleration is defined as the change in velocity over a given time interval. In this question, you are given the initial velocity, final velocity, and the time taken for the change in velocity. To find the acceleration, you need to use the formula: acceleration = (change in velocity) / (time interval). Substitute the given values into the formula and calculate the answer in units of m/s/s.

Question 3:
This question involves understanding the motion of a ball thrown in the air without air friction. Consider the behavior of the ball during its upward and downward motion. Read through each option and analyze how the two flash photos would reflect the behavior of the ball. Determine which option aligns with the absence of air friction.

Question 4:
This question involves understanding the behavior of an object in free fall. Consider the velocity and acceleration at different points during the fall. Read through each statement and determine which one accurately describes the behavior of the object during free fall.

Question 5:
To measure the speed of a moving object using a stopwatch and a meter stick, you need to measure the time it takes for the object to travel a certain distance and the distance it traveled. Read through each option carefully and determine which step-by-step process correctly measures the speed using the given tools.

Remember, it's always important to critically think and reason through each question to come up with the most accurate answer. If you have any specific questions while trying to find the answers, feel free to ask!
