Answer:
B) a= 2.6 m/s²
Explanation:
Conceptual analysis:
Because the car moves with uniformly accelerated movement, we apply the following formula :
vf= v₀+a*t Formula (1)
Where:
t : time in seconds (s)
v₀: initial speed in m/s
vf: final speed in m/s
a: acceleration in m/s²
Known Data
v₀=0
vf = 24 m/s
t= 9.4
Development problem
We replace the data in the formula (1)
vf= v₀+a*t
24 m/s = 0 + a*9.4s
a = (24 m/s) / (9.4s)
a= 2.6 m/s²
