A particle moves along the x axis. Its position varies with time acording to the expression x =-4t + 2t2
Average and Instantaneous Velocity
A particle moves along the x axis. Its position varies with time acording to the expression x =-4t + 2t2, where x is in meters and t is in seconds. The position-time graph for this motion is shown in the figure. Notice that the particle moves in the negative x direction for the first second of motion, is momentarily at rest at the moment t = 1 s, and moves in the positive x direction at times t >> 1s
(A) Determine the displacement of the particle in the time intervals t = 0 to t = 1 s and t = 1 s to t = 3 s.
(B) Calculate the average velocity during these two time intervals
(C) Find the instantaneous velocity of the particle at t = 2.5 s.
