Acceleration is sometimes expressed in multiples of g, where g=9.8 m/s2 is the acceleration due to gravity. In a car crash, the cars velocity changes from 30 m/s to 0 m/s in 0.15s. In terms of g, what is the acceleration of the car.

Suggested Answer

[tex]a = \frac{\Delta v}{t}
\\a= \frac{30}{0.15}
\\a = 200 ms^-2 [/tex]in terms of g:[tex]a = 200/9.8 g= 20.40...g

a = 20.4g (3s.f)[/tex]
