A particle moves along a line so that its position at any time t ≥: 0 is given hy the function 5(t) = t/2- 3t + 2. where s is measured in meters and t is measured in seconds.
a) Find the displacement during the first 5 seconds.
b) Find the average velocity during the first 5 seconds.
c) Find the instantaneous velocity when t = 4.
d) Find the accel.ellltion of the particle when t = 4.
e) At what values oft does the particle change direction?
f) Where is the particle when is a minimum?
