Motion problems using antiderivatives

Then we'll take it from there.In summary, an object with a velocity of 6t-3t^2 in metres per second moves in a straight line. In the first second, it travels a distance of 1.5 meters. In the first two seconds, it travels a distance of 3 meters. When t=3, the object is back where it started and has traveled a total distance of 9 meters.

Homework Statement



An object moves in a straight line with velocity v = 6t-3t^2, where v is measured in metres per second.
a) how far does the object move in the first sec?
b) how far does the object move in the first two seconds?
c) the object is back where it started when t=3. how far did it travel to get there?


Homework Equations





The Attempt at a Solution



the only bit i got was the anti derivative s=3t^2-t^3+c

help is requested :D

a) should be pretty easy. It's the difference between s when t=1 and s when t=0, isn't it? Try working that out first.
 

What is motion?

Motion is the change in position of an object over time.

How can antiderivatives be used to solve motion problems?

Antiderivatives can be used to find the original function from its derivative, which in motion problems, represents the velocity of an object. By finding the antiderivative of the velocity function, we can then determine the position of the object at any given time.

What are the steps to solving a motion problem using antiderivatives?

The first step is to identify the function representing the velocity of the object. Then, find its antiderivative to get the function for position. Next, plug in the given time values to determine the positions at those times. Finally, interpret the results in the context of the problem.

What are the units of measurement for velocity and position in motion problems?

Velocity is measured in distance per time, such as meters per second or miles per hour. Position is measured in units of distance, such as meters or miles.

Are there any limitations to using antiderivatives to solve motion problems?

Yes, antiderivatives can only be used for objects with constant acceleration. If the object has varying acceleration, more advanced tools such as the Fundamental Theorem of Calculus may be needed.
