Homework Help Overview

The discussion revolves around calculating velocity from kinetic energy in a physics context. The original poster presents a scenario with given velocities and corresponding kinetic energies, seeking to determine a new velocity based on an increase in kinetic energy.

Discussion Character

  • Exploratory, Mathematical reasoning

Approaches and Questions Raised

  • Participants explore the relationship between kinetic energy and velocity, with some suggesting the need to find mass from earlier equations. Others mention the kinetic energy formula and discuss how knowing mass could simplify the problem.

Discussion Status

There is an ongoing exploration of how to approach the problem, with some participants providing hints and guidance on using the kinetic energy formula. The original poster has clarified the mass involved, which may help in progressing the discussion.

Contextual Notes

The original poster has specified the mass as 1200 kg, which is a critical piece of information for solving the problem. There is an emphasis on not just providing the answer but understanding the process involved.

I know 4 thing
Velocity 10m/s KE = 60000
Velocity 15m/s KE = 135000

For the next velocity the KE raises antoher 105000

and the new Velocity = ? and KE = 240000

How do I solv the new Velocity...

Can you find the mass from either of the first two equations? If yes, will that help with your final answer?
 
well K.E. = 1/2mv^2

if you knew "m", the rest would be easy
 
if the unit of energy is jule then
20 m/s

enjoy
 
Help!

Yeah I forgot...the mass is 1200kg please tell me how to do it not only show the answer ...

Just plug that info into the K.E formula. You know the Kinetic energy and the mass, now find the velocity.
 
Thx guys had some problems there ...
