Question

Chapter 02, Problem 62 Your answer is partially correct. Try again. A model rocket blasts off from the ground, rising straight upward with a constant acceleration that has a magnitude of 97.7 m/s2 for 1.53 seconds, at which point its fuel abruptly runs out. Air resistance has no effect on its flight. What maximum altitude (above the ground) will the rocket reach?

Answer 1

I Givent a =97.7 misec , time = 1.53 m/sec So we know, s=ut that . Here, U=0 Initial speed of socket . S = height achieved by rocket ? S=0+4197.7) t = {(37.5)(1.53) = 114.35 m So, height achieved will be [114.35m/ now,
