Question

Ou

Answer 1

Answer:

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  + $\frac{1}{2}$ 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  =  $\frac{1}{2}$ at²

     130 =  $\frac{1}{2}$  x a x 5.5²  

     130  = 15.13a

         a  = 8.6m/s²
