Question 1123027: Vivian is walking to the hair dresser’s at 1.0 m/s when she glances at her watch and realizes that she is going to be late for her appointment. Vivian gradually quickens her pace at a rate of 0.100 m/s^2. What is Vivian’s speed after 8.2s ? Answer by ikleyn(52803) (Show Source):
For the uniformly accelerated rectilinear movement
V = + ,
where is an in initial speed, "a" is an acceleration and t is the time.
In your case = 1.0 m/s, a = 0.1 m/s^2 and t = 8.2 s.
Substitute this data into the formula and calculate.
