Question

A truck is driving 500 meters/minute. He slows down to a complete stop over 0.25minutes. Calculate his acceleration.

Answer 1

Given

The velocity is v=500 meters/minute

The time taken is t=0.25 minute

To find

The acceleration

Explanation

We know,

The acceleration is the ratio of velocity to time.

Thus,

$\begin{gathered} a=\frac{v}{t} \\ \Rightarrow a=\frac{500}{0.25} \\ \Rightarrow a=2000\text{ m/min}^2 \end{gathered}$

Conclusion

The acceleration is

$2000\text{ m/min}^2$
