Answer:

8.6m/s²

Step-by-step 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 +
(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 =
(1)/(2) at²

130 =
(1)/(2) x a x 5.5²

130 = 15.13a

a = 8.6m/s²
