Solve each part of following problem given below:
Problem: A model rocket rises with constant acceleration to a height of 3.7m , at which point its speed is 26.0m/s.
Part I: How much time does it take for the rocket to reach this height?
Part II: What was the magnitude of the rocket's acceleration?
Part III: Find the height of the rocket 0.10s after launch.
Part IV: Find the speed of the rocket 0.10s after launch.
I need help to solve the above problem and express your answer using two significant figures.
