Answer:
a = 4.59 m/s²
Step-by-step explanation:
given,
initial speed of the car = 0 m/s
final speed of the car = 145 km/h
1 Km/h = 0.278 m/s
145 Km/h = 145 x 0.278 = 40.31 m/s
time, t = 8.78 m/s
Acceleration of car before collision
a = 4.59 m/s²
The magnitude of acceleration before collision is 4.59 m/s²
