Hi, I have this question where a rocket is launched up into the air and I'm given the verticle (14ft) and horizontal (18ft) height and it's asking for the velocity and I have no idea where to start. If someone could help me that would be awesome.

Where are you in school? Why are you being given a problem for which you don't understand the basic concepts?

I'm in college and I'm actually really confused on how to start it since there's only 2 pieces of information.

Hi zahresh walji. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif

This "New Member Introductions" forum is for introducing yourself (and testing that your messages are posting okay). If you wish to ask technical questions, please choose a forum appropriate to that, and not this one. A good habit to adopt is to always look through some existing threads in any forum before you begin your own thread, that way you make a preliminary check that it is going to be appropriate.

Choose from those available for homework-type questions here: https://www.physicsforums.com/forums/homework-and-coursework-questions.152/

I hope you find your time is well spent here at Physics Forums.

Restart your technical question as a thread in the General Physics forum and I"ll give you the next step (you DO have another piece of information)

See NascentOxygen, please start a thread in the homework section for homework problems.
 

FAQ: Calculating Velocity of a Launched Rocket: Solving a Projectile Motion Problem

What is projectile motion?

Projectile motion is the motion of an object through the air or space under the influence of gravity. It follows a curved path known as a parabola.

How do you calculate the velocity of a launched rocket?

The velocity of a launched rocket can be calculated using the formula v = u + at, where v is final velocity, u is initial velocity, a is acceleration, and t is time. In the case of projectile motion, the initial velocity will have both horizontal and vertical components.

What is the difference between initial velocity and final velocity?

Initial velocity is the velocity at the beginning of the motion, while final velocity is the velocity at the end of the motion. In projectile motion, the initial velocity is the velocity at which the object is launched, and the final velocity is the velocity at the highest point of the trajectory.

How does the angle of launch affect the velocity of a rocket?

The angle of launch affects the velocity of a rocket by determining the initial vertical and horizontal components of the velocity. A higher angle of launch will result in a higher initial vertical velocity and a lower initial horizontal velocity, while a lower angle of launch will result in a lower initial vertical velocity and a higher initial horizontal velocity.

What factors can affect the accuracy of calculating the velocity of a launched rocket?

Some factors that can affect the accuracy of calculating the velocity of a launched rocket include air resistance, wind, and the precision of the measurement tools used. These factors can cause variations in the actual trajectory of the rocket, which can affect the calculated velocity.
