four times
speed and time
To accelerate an object twice as fast, you would need to exert twice the force. This is because force is directly proportional to acceleration, as defined by Newton's second law, F=ma. So if you double the acceleration, you must double the force.
twice as fast as my mum
About twice as fast as the cold cakes. (:
Twice as fast as half its speed.
as fast it can go
over 120mph.
A minim note is twice faster than a semibreve.
