# College Physics 2.19 – Acceleration of an intercontinental ballistic missile

## Solution:

The formula for acceleration is

$\displaystyle \text{a}=\frac{\text{v}_{\text{f}}-\text{v}_0}{\text{t}}$

Substituting the given values

$\displaystyle \text{a}=\frac{6.5\times 10^3\:\text{m/s}-0\:\text{m/s}}{60.0\:\text{sec}}=108.33\:\text{m/s}^2$

This can be expressed in multiples of g

$\displaystyle \text{a}=\frac{108.33\:\text{m/s}^2}{9.80\:\text{m/s}^2}=11.05\text{g}$

Therefore, the average acceleration is 108.33 m/s2 and can be expressed as 11.05g.
