MTH132 - Examples: Graphs and Position Functions of Particles, Exercises of Physics

Examples and problems related to the graphs and position functions of particles in physics. Students are asked to determine when each particle is speeding up or slowing down based on the given graphs. Additionally, students are required to find velocities, accelerations, and distances for various position functions. Useful for university students taking a physics course.

What you will learn

  • When is particle (a) in example 1 speeding up and when is it slowing down?
  • Find the velocity of the particle in example 3 at time t = 2 seconds.
  • When is particle (b) in example 1 speeding up and when is it slowing down?
  • Find the total distance traveled by the particle in example 3 in the first 8 seconds.
  • When is the particle in example 3 at rest?
