A rocket sled is propelled by a solid propellant rocket motor of 6.568×105 N thrust. If the sled travels 1.719×103 m while attaining a top speed of 7.660×102 m/s. What is its average acceleration?

Respuesta :

Answer:The average acceleration of the sled is [tex]170.66 m/s^2[/tex]

Explanation:

Initial Velocity of the rocket ,u=  0 m/s

Final Velocity of the rocket ,v= [tex]7.660\times 10^{2} m/s[/tex]

Distance covered by the sled,s = [tex]1.719\times 10^{3} m[/tex]

[tex]v^2-u^2=2as[/tex] (Third equation of motion)

[tex](7.660\times 10^{2} m/s)^2-(0 m/s)^2=2a(1.719\times 10^{3} m)[/tex]

[tex]a=170.66 m/s^2[/tex]

The average acceleration of the sled is [tex]170.66 m/s^2[/tex]
