11.In order to double kinetic energy, the speed should beA) increased by the factor of twoB) increased by the factor of V2C) decreased by the factor of twoD) decreased by the factor of 2

Answer :

The kinetic energy of the object is,

[tex]K=\frac{1}{2}mv^2[/tex]

Here, K is kinetic energy, m is the mass and v is the speed.

Since the kinetic energy depends upon the square of speed of object therefore, to double the kinetic energy the speed should be increased by factor square root of 2. Mathematically, it is given as,
