Answer:
a= -12.64 m/s²
The negative sign means deceleration, which shows that the limousine was slowing down to stop.
Explanation:
The formula for acceleration is :
a= change in velocity / time
[tex]a=v_f-v_i/t\\[/tex]
where;
[tex]v_f=0km/h\\\\v_i=55km/h\\\\t=4.352s[/tex]
a= 0-55 /4.352 = -55/4.352 = -12.64 m/s²
The negative sign means deceleration, which shows that the limousine was slowing down to stop.
