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).

Answer: Socratic
Explanation: i’m not sure but you can use Socratic it’s a good app that helps
The negative work done states that the work is done by the object and not on the object.
<u>Explanation:
</u>
According to work energy theorem, the work done is equal to change in kinetic energy exhibited by the body. As the mass of the object is constant, and the velocity is decreased from 10 m/s to 4 m/s, the work done will be
Here W is the work done, m is the mass and v is the final and u is the initial velocity of the object. As the initial velocity is greater than the final velocity. So
So the work done is negative for the given situation. The negative work done states that the work is done by the object and not on the object.
