Answer:
[tex]a=242.62\ m/s^2[/tex]
Explanation:
The rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds.
We need to find the acceleration of the rocket. Initially it was at rest, u = 0
Acceleration = rate of change of velocity
[tex]a=\dfrac{444\ m/s}{1.83\ s}\\\\a=242.62\ m/s^2[/tex]
So, the acceleration of the rocket is [tex]242.62\ m/s^2[/tex].
