The Acceleration of a model rocket = 4 m/s²
<h3>Further explanation </h3>Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
An upward thrust of 35 N
A model rocket has a mass of 2.5 kg(weight = 25 N)
so resultant force :
The acceleration :
According to Charles' Law the volume of an ideal gas is directly proportional to its absolute temperature in Kelvin keeping the pressure constant.
V∝ T, P is constant
where V, T and P are volume, temperature and pressure
=
where V₁, T₁, V₂ and T₂ are initial volume, initial temperature, final volume and final temperature.
