SUMMARY

A rocket accelerates upward at 29.0 m/s² for 8.00 seconds, starting from rest. The final velocity at the end of this period is calculated using the formula v = a * t, resulting in a final velocity of 232 m/s. The height reached by the rocket can be determined using the displacement formula deltaX = (1/2) * final velocity * change in time, leading to a total height of 928 meters above the ground.

PREREQUISITES
  • Understanding of kinematic equations for uniformly accelerated motion
  • Knowledge of basic physics concepts such as acceleration and velocity
  • Familiarity with the formula for calculating displacement
  • Ability to perform unit conversions and calculations in physics
NEXT STEPS
  • Study kinematic equations in detail, focusing on displacement and velocity calculations
  • Learn about the effects of gravity on projectile motion
  • Explore real-world applications of acceleration in rocketry
  • Investigate the concept of fuel consumption and its impact on rocket motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and kinematics, as well as educators looking for practical examples of motion under constant acceleration.

Homework Statement



A rocket moves upward, starting from rest with an acceleration of 29.0 m/s^2 for 8.00 s. It runs out of fuel at the end of the 8.00 s but does not stop. How high does it rise above the ground? (in meters)


Homework Equations



deltaX=(1/2)final velocity * change in time ?

The Attempt at a Solution




i really don't understand which of the equations of straight-line motion would be relevant, and how, for example: 29m/s^2 is DIFFERENT than just 29m/s

Yes, 29.0 is the acceleration not velocity... what are your displacement equations for uniform acceleration?
