AI Thread Summary
To calculate the new velocity given a kinetic energy of 240,000 J and a mass of 1,200 kg, the kinetic energy formula K.E. = 1/2 mv^2 can be used. Rearranging this formula to solve for velocity (v) gives v = sqrt(2 * K.E. / m). Plugging in the values, v = sqrt(2 * 240,000 J / 1,200 kg), which simplifies to v = 20 m/s. This method effectively determines the velocity using the known mass and kinetic energy. Understanding the relationship between kinetic energy and velocity is crucial for solving such problems.

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 ...
