Question

A powerful missile reaches a speed of 5 kilometers per second in 10 seconds after its launch. What is the average acceleration of the missile during this period?

Answer 1

This would mean that it went 5 km for 10 seconds
5 x 10= 50km during that period of time

Answer 2

First of all, you need to know the right formula for the answer.

The formula to calculate the average acceleration is:

Average acceleration = Change in speed / Change in time

First of all, we need to transform these 5 kilometers into meters, and with that, we have that the missile moves from the 0s point to the 10s point with an average speed of 5000m/s.

So, as you know, he starts with no speed and from 0s in time, the formula will be like this:

5000m/s-0m/s / 10s-0s

With this, the final result is 500m/s^2.
