It would be 4000 joules.
You can be twice as certain about your speed now.
Twice the speed of sound is called Mach 2. This means an object is traveling at twice the speed of sound, around 1,522 miles per hour at sea level.
Work done=Heat in-Heat out 2000-1500=500J
The momentum would be twice as much. Momentum is directly proportional to mass, so if the mass doubles while the speed remains the same, the momentum will also double.
340.29 m/s

Twice the Speed of Life was created on 2004-10-26.
Nothing physical is believed to be able to travel twice the speed of light.
Twice the speed of sound is called Mach 2. This means an object is traveling at twice the speed of sound, around 1,522 miles per hour at sea level.
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.

There is currently no commercial airliner which can travel at that speed.

Twice as fast as half its speed.
