to estimate its velocity
in km/h at t = 40 min. Example: PHYS 1L03, Fall 2013, McMaster University, R. Nejat OneDimensional Motion
Example:
• The position of a particle as a function of time is
given by the curve shown below. Find the
instantaneous velocity at time t = 2 s. When is the
velocity greatest? When is it zero? Is it ever
negative? What is the average velocity of this
particle between t = 2 s and t = 5s? PHYS 1L03, Fall 2013, McMaster University, R. Nejat OneDimensional Motion
Example: velocity at t=2 s? Greatest velocity ? PHYS 1L03, Fall 2013, McMaster University, R. Nejat PHYS 1L03, Fall 2013, McMaster University, R. Nejat 8 OneDimensional Motion OneDimensional Motion Example:
Zero velocity? Negative velocity? Average velocity?
• Having the same top speed, how an African lion
can catch a Cape buffalo?
