Question

a 0.200kg model rocket is observed to rise 100m above the ground after launch. what was the launch speed of the rocket at the ground?

Answer 1

The answer to your question is 44.27 m/s

Answer 2

The speed is around 4.33 meters per second.

Step-by-step explanation:

In this case, the speed is defined with the following formula

`v=√(2gh)`

Where
`g=9.81m/s^(2)` and
`h=100m`.

Replacing these values, we have

`v=√(2(9.81)(100))=√(1962)\approx 44.3 m/s`

Therefore, the speed is around 4.33 meters per second.
