Question

Calculate the acceleration of a car that can go from rest to 100 km/h in 10 seconds

Answer 1

Answer: $2.77 m/s^{2}$

Explanation:

Acceleration $a$ is defined as the variation of velocity $\Delta V$ with time $\Delta t$:

$a=\frac{\Delta V}{\Delta t}$

Where:

$\Delta V=100km/h-0km/h=100km/h=27.77m/s$

$\Delta t=10 s$

$a=\frac{27.77m/s}{10 s}$

Finally:

$a=2.77m/s^{2}$
