Ou A truck starts from rest and accelerates uniformly over a time of 5.5 seconds for a
distance of 130 m. Determine the acceleration (in m/s^2) of the truck.
Please submit your answer with 2 decimal places!

8.6m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time  = 5.5s

Distance  = 130m

Unknown:

Acceleration  = ?

Solution:

To solve this problem, we use one of the appropriate motion equations:

       S  = Ut  + at²

S is the distance

U is the initial velocity

t is the time taken

a  is the unknown acceleration

t is time taken

    Since U = 0m/s

      S  =   at²

     130 =    x a x 5.5²  

     130  = 15.13a

         a  = 8.6m/s²
