Answer:
20.4
Explanation:
Average acceleration is the change in velocity over time.
a = (v − u) / t
where a is acceleration,
v is final velocity,
u is initial velocity,
and t is time.
Given v = 0 m/s, u = 30 m/s, and t = 0.15 s:
a = (0 − 30) / 0.15
a = -200 m/s²
As a multiple of g, the magnitude of the acceleration is:
|a| = 200 m/s² × (1 g / 9.8 m/s²) = 20.4g
The driver experiences 20.4 g's.
