I- 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 t 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 t> 1 s. (A) Determine the displacement of the particle in the time intervals t= 0 to 1=Is and t = 1s to 1 = 3 s. B) Calculate the average velocity during these two-time intervals C) determine the instantancous velocity and instantaneous speed at t= 0.5 s.

I- 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 t>1 s.
(A) Determine the displacement of the particle in the time intervals t= 0 to t = I s and t=Is
to t= 3 s.
B) Calculate the average velocity during these two-time intervals
C) determine the instantaneous velocity and instantaneous speed at t= 0.5 s.
