A model rocket is constructed with a motor that can provide a total impulse of 25.5 N · s. The mass of the rocket is 0.213 kg. What is the speed that this rocket achieves when launched from rest? Neglect the effects of gravity and air resistance.

Impulse (N) = mv(final) - mv(initial)

Yes

Your welcum

so whats the answer than?

yo mama

thats the answer

To find the speed the rocket achieves when launched from rest, we can use the principle of conservation of momentum. The equation for impulse is given by:

Impulse = Force * Time = Mass * Change in Velocity

Given that the total impulse is 25.5 N · s and the mass of the rocket is 0.213 kg, we can rearrange the equation to solve for the change in velocity:

Change in Velocity = Impulse / Mass

Change in Velocity = 25.5 N · s / 0.213 kg

Change in Velocity = 119.7182 m/s

Since the rocket starts from rest, the initial velocity is zero. Therefore, the final velocity is equal to the change in velocity:

Final Velocity = Change in Velocity = 119.7182 m/s

Thus, the speed that the rocket achieves when launched from rest is 119.7182 m/s.
