A model rocket engine has an average thrust of 5.26N . It has an initial mass of 25.5g , which includes fuel mass of 12.7g. The
1 answer:
Thrust given = 5.26N
Δmass = 12.7g
Δtime = 1.9seconds
exhaust speed = ve
The thrust acting on the rocket is = veΔm/ Δt
So, ve = thrust / (Δm/Δt) = 5.26 x 1.9/12.7 x
ve = 707 m/s
<h3>What is Thrust?</h3>- Newton's third law uses the concept of thrust to quantitatively quantify a reaction force. A force of similar size and in the opposite direction will be applied to a system when mass is expended or accelerated in one direction.
- Thrust is another name for the force that is exerted to a surface normal to or perpendicular to it.
- The amount required to propel 1 kilogramme of mass at a velocity of 1 metre per second per second is measured as force, and hence thrust, using the International System of Units (SI) in newtons (symbol: N).
