Motion problems using antiderivatives

Click For Summary
SUMMARY

The discussion focuses on solving motion problems using antiderivatives, specifically for an object with a velocity function defined as v = 6t - 3t². The key solutions involve calculating the distance traveled in the first second and the first two seconds, as well as determining the total distance traveled when the object returns to its starting point at t = 3 seconds. The antiderivative of the velocity function is correctly identified as s = 3t² - t³ + c, which is essential for finding the position function.

PREREQUISITES
  • Understanding of antiderivatives and integration techniques
  • Familiarity with motion equations in physics
  • Knowledge of polynomial functions and their properties
  • Basic calculus concepts, particularly related to velocity and displacement
NEXT STEPS
  • Practice calculating definite integrals to find distances over specific time intervals
  • Explore the relationship between velocity, acceleration, and displacement in motion problems
  • Learn about the Fundamental Theorem of Calculus and its applications in physics
  • Investigate more complex motion problems involving variable acceleration
USEFUL FOR

Students studying calculus, physics enthusiasts, and anyone looking to deepen their understanding of motion analysis through antiderivatives.

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.
