Transcribed Image Text:1- A particle moves along the x axis. Its position varies with time according to the expression
x=- 41 + 2r where x is in meters and r is in seconds. The position-time graph for this motion
is shown in Figure. Note 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 1>Is.
(A) Determine the displacement of the particle in the time intervals t= 0 to t = Is and t=1s
to = 3s.
B) Calculate the average velocity during these two-time intervals
C) determine the instantaneous velocity and instantaneous speed at t= 0.5 s.
