Show the velocity graph of a 4.7 kg object as it moves along the x-axis

In summary, the y-axis multiplied by the mass of 4.7 (in kg) represents the momentum at a specific time on a velocity-time graph. This can be calculated using the equation ##F=\frac{dp}{dt}##.

Homework Statement
Figure 1 shows the velocity graph of a 4.7 kg object as it moves along the x-axis.
A) What is the x- component of the net force acting on this object at t = 1s?
B) At 3s?
C) At 7s?
Relevant Equations
F=M•a
If force= m•a would the answer just be the y-axis • 4.7 at the specific time such as
A) 4.7 • 6 = 28.2?
B) 4.7 • 12= 56.4
C) 4.7 • 3 = 14.1

Post Figure 1. (If you have a velocity-time graph, how would you find the acceleration at any point?)

I solved it! Sorry for the late response, if you’re still wondering.

Since the y-axis shows velocity (in m/s) multiplying the y-axis by the mass of 4.7 (in kg) yields momentum (in kg m/s).

A relevant equation would be: ##F=\frac{dp}{dt}##
 

Related to Show the velocity graph of a 4.7 kg object as it moves along the x-axis

1. How do you plot the velocity graph of a 4.7 kg object?

To plot the velocity graph of a 4.7 kg object, you will need to measure the object's position at different points along the x-axis and calculate its velocity using the formula v = Δx/Δt. Then, plot the velocity values on the y-axis against the corresponding time values on the x-axis.

2. What does the slope of the velocity graph represent?

The slope of the velocity graph represents the object's acceleration. A positive slope indicates that the object is accelerating in the positive direction, while a negative slope indicates deceleration or acceleration in the negative direction.

3. How can you determine the object's average velocity from the graph?

The object's average velocity can be determined by finding the slope of the line connecting the initial and final velocity points on the graph. This slope represents the object's average velocity over the given time interval.

4. Can the velocity graph show the object's direction of motion?

No, the velocity graph only shows the object's speed and direction of motion cannot be determined from it. However, the direction of motion can be inferred from the slope of the graph. A positive slope indicates motion in the positive direction, while a negative slope indicates motion in the negative direction.

5. How does the mass of the object affect the velocity graph?

The mass of the object does not affect the shape or slope of the velocity graph. However, a heavier object may require more force to accelerate and thus may have a steeper slope on the graph compared to a lighter object with the same velocity.
