Answer:
2.22 m
Explanation:
According to literature, the highest abrupt deceleration the human body can experience and survive in a car accident is 250 m/s²
Using the equations of motion,
v² = u² + 2as
v = final velocity of the body = 0 m/s
u = initial velocity of the body = 120 km/h = 120 × 1000/3600 = 33.33 m/s
a = - 250 m/s²
s = ?
0² = 33.33² - (2×250×s)
500s = 1111.1111
s = 2.22 m
