Answer:
a = 200 m/s²
Explanation:
Given,
The initial speed of rocket-powered sled, u = 0
The final speed of rocket-powered sled, v = 440 m/s
Time taken to reach final speed, t = 2.20 s
The acceleration of the body is given by the change in velocity by time
a = (v - u) / t
= (440 - 0) / 2.20
= 200 m/s²
Therefore, the acceleration of the rocket-powered sled, a = 200 m/s²
