Work Step by Step

First draw the object in the diagram in its initial and final positions, which should not be to-scale but should be in an appropriate direction for the problem. For a rocket taking off, an initial point on the ground and a final point above in the air are reasonable. Identify the variables which are provided in the question. we are given a final velocity of 200 m/s and a final position of 1.0 km. It can be inferred from the question that the rocket begins on the ground with initial position, velocity, time equal to 0. Label the unknown variables that would need to be found for the problem. The unknowns for the rocket are the final time and acceleration needed to reach the final velocity and height specified by the question.
