Vertical Motion of a Rocket

Q: A rocket moves upward, starting from rest with an acceleration of 27.2 m/s2 for 3.49 s. It runs out of fuel at the end of the 3.49 s, but does not stop. How high does it rise above the ground?

A: Okay the rocket’s moving up with an acceleration of +27.2m/s^2 for a . . . → Read More: Vertical Motion of a Rocket

Tips to Remember for Kinematics and Projectile Questions

Some things you should know for projectiles (note that you haven’t done anything with angles yet, so you can ignore the sine and cosine parts):

The vertical and horizontal components are independent of each other. The vertical velocity is usually Vy = V*sin(Ď´) horizontal velocity is usually Vx = V*cos(Ď´), where V is the . . . → Read More: Tips to Remember for Kinematics and Projectile Questions
