In summary, when solving for the velocity of a toy car using the area under a graph, it is important to remember to use integrals and to consider the relationship between force, time, and velocity. Simply adding up the areas of the different shapes on the graph is not an effective method and can lead to incorrect results. Additionally, it is important to take into account the initial conditions and the mass of the object when calculating the final velocity.

Well, what do you know about how force relates to the motion of an object?sidt36 said:
Trying random things with a graph rarely leads to anything useful, unless you know something about the physics of what is going on.

Well i know that Force * time leads to mass delta velocity

Have you done any work with integrals and areas? Integrals and force, momentum and time?

And i have not done integrals. I have to solve it with a 9th graders knowledge

Everything looks OK with your calculations, you just need to put them together.sidt36 said:
For the first part of the calculation, you are told that the toy car is at rest initially, so this means that v(t) = 0 m/s when t = 0 sec.
What would be the velocity of the car after 4 seconds, using your figures for the change in velocity?
Don't forget to use the mass of the toy car!

Yup got it 6.5 i cap is the answer
FAQ: How Do I Interpret This Graph for Homework?
What do the axes represent on this graph?
The vertical (y) axis represents the dependent variable, while the horizontal (x) axis represents the independent variable. This means that the changes in the dependent variable are a result of changes in the independent variable.
How do I read the data points on the graph?
The data points on the graph represent the relationship between the two variables being measured. The closer the data points are to the trend line, the stronger the correlation between the variables.
What does the shape of the graph indicate?
The shape of the graph can indicate the type of relationship between the variables being measured. A linear graph with a straight trend line indicates a positive or negative correlation, while a curved graph may indicate a non-linear relationship.
How do I determine the units of measurement for each axis?
The units of measurement for each axis are typically labeled on the graph. If not, you can refer to the data or legend provided with the graph to determine the units for each variable.
How can I use this graph to make predictions or draw conclusions?
To make predictions or draw conclusions, you can analyze the trend line and the data points on the graph. If the trend line is strong and the data points are close to the line, you can make accurate predictions about the relationship between the variables. Additionally, you can compare the data points to any relevant benchmarks or standards to draw conclusions about the data.
