adell [148]

Answer:

11.9051g

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.8 m/s²

$v=u+at\\\Rightarrow a=\dfrac{v-u}{t}\\\Rightarrow a=\frac{70-140}{0.6}\\\Rightarrow a=-116.67\ m/s^2$

Absolute value of the (negative) average acceleration is 116.67 m/s²

$\dfrac{a}{g}=\dfrac{116.67}{9.8}\\\Rightarrow a=11.9051g$

The deceleration was 11.9051g
