Amodel rocket rises from rest with constant acceleration of 106m/s2.what is the rocket speed at a height of 3.2m

At a height of 3.2 meters, the final speed of the model rocket is 26.05 m/s.

Given the following data:

To find the final speed of the model rocket, we would use the third equation of motion;

Where:

Substituting the given parameters into the formula, we have;

Final velocity, V = 26.05 m/s

We can solve the problem by using the following equation:

where

vf is the final speed of the rocket

vi=0 is the initial speed of the rocket (it starts from rest)

is the rocket's acceleration

S=3.2 m is the distance covered by the rocket

Re-arranging the equation, we find the velocity of the rocket after 3.2 m:
